Page 31: General Description
Description functions. The 3152B is a digital waveform generator that creates virtually any Output type of waveform. Unlike conventional function and pulse generators, the 3152B creates waveforms digitally and stores them Waveforms in memory.
Page 32: Run Modes
The 3152B has two run modes that determine when it will output a Run Modes waveform. Continuous Run is the basic mode for generating a waveform that does not stop. This mode is appropriate except when the application requires synchronization to external events.

Page 35: Specifications
Signal Amplifier module. The description in this manual ignores specific configurations and provides details of the 3152B only. The configuration chosen can have a significant impact on the way that one programs the instrument. Register based commands are parsed and executed using an external dll (3100R) but message-based commands are parsed and executed by the internal CPU (3100M).
Page 36: Safety Considerations
Publication No. 980935 Rev. A 3152B User Manual Figure 1-6, Configurations: 3151B, 3152B, 3100R-3152B, and 3100M-3152B The 3152B has been manufactured according to international CE Safety safety standards – EN-61010.

Page 38: Output (Out)
Continuous mode. When placed in Trigger, (TRG/PLL) Gated, or Burst mode, the trigger input is active, and the 3152B waits for the proper condition to trigger the instrument. In Trigger and Burst modes, the TRIG/PLL input is edge-sensitive, so that a signal transition will trigger the 3152B.
Page 39: Ext Sclk
This input accepts a 10MHz reference signal and is labeled as PM EXT 10MHz IN on the 3152B but can be programmed as either function. At the factory, this input is configured for TTL logic levels. It may be changed to 0 dBm, but only by qualified service personnel.
Page 40: Arbitrary (User) Waveforms
Each waveform has parameters for modifying it to suit your requirements. The waveform memory can store one or more arbitrary, or user- Arbitrary (User) defined, waveforms. The regular 3152B configuration is supplied with 1 mega-sample (M-sample). A 4 M-sample waveform memory Waveforms option is available on the 3100M/R-3152B models.

Page 42: Modulated Waveforms
Figure 1-10, Sequenced Waveforms The use of direct digital synthesis (DDS) technology makes the Modulated 3152B is agile. During operations such as sweep, FSK, FM, and other modulation modes, the 3152B quickly synthesizes the Waveforms modulated waveform using the DDS circuit. The variety of modulated waveforms are described below.
Page 43: Frequency Hopping
The amplitude hopping function causes the output amplitude to hop Amplitude Hopping through an amplitude list. The amount of time the 3152B dwells on an amplitude level is programmable for each hop. You may also set the dwell time uniformly over the entire hop list.
Page 44: Digital Pulse Waveforms
You may operate the 3D function only from the ArbConnection utility. The waveform memory of the 3152B can be programmed as if it Digital Pulse were a pulse generator. All pulse parameters are adjustable,...
Page 45: Continuous Mode
The sources to trigger a burst are the same as for the Triggered mode. The 3152B responds to a variety of trigger sources such as the Trigger Sources TRIG/PLL connector, backplane trigger lines (TTLTrg0-7), and a software trigger.
Page 46: Modulation Run Modes
When that waveform has completed, the instrument resumes outputting non-modulated waveforms. The second option is where the 3152B, before receiving a trigger or gate, outputs a DC level. When triggered or gated, the 3152B outputs the modulated waveform. When that waveform has completed, the instrument resumes outputting a DC level.
Page 47: Phase Modulation
The TRIG/PLL input has a programmable trigger level and programmable slope. When the 3152B is placed in PLL mode, there are two ways to Phase control the phase offset. The first way is to modify the phase offset setting using SCPI commands.

Page 56: Chapter 3 Operation
Chapter 3 Operation Overview This chapter explains how to operate the 3152B. Unlike a bench-top instrument, the 3152B requires a computer to turn on functions, change parameters, and configure various operating modes. Two software applications are available to control the instrument: VXIplug&play soft front panels (SFPs) and ArbConnection.
Page 57: Output Termination
Appendix A specifies the level of protection Protection for each input or output connector. At power-up or as a result of a software reset, the 3152B changes Power On/Reset all settings to their default values. Chapter 4 lists all settings and...
Page 58: Turning The Output On
Turns the output off outp 0 The 3152B defaults to a 1 MHz, 5 Vp-p sine wave when you apply power or reset the unit. If you turn the output on before changing any settings, the output defaults to a sine wave signal.

Page 62: Continuous Run Mode
If you have not invoked any interrupted modes since applying power to the 3152B, you may use the following command to turn off Continuous mode and default to Triggered mode: Turns off Continuous mode, changing to init:cont off an interrupted mode.
Page 63: Re-Triggered Run Mode
This turns off Re-triggered mode. The trig:retr 0 generator will revert to the Triggered run mode. This removes the 3152B from interrupted init:cont on run mode and reverts to Continuous mode. In Gated mode, the output remains at a specific DC level until a Gated Run Mode valid event opens the gate.
Page 64: Burst Run Mode
Each time a transition at the trigger input occurs, the 3152B generates a counted burst of output waveforms. At the end of the burst, the output assumes a DC level equal to the amplitude of the first point of the waveform.
Page 65: Selecting The Trigger Source
• Software trigger. Your software may generate an interrupt condition by executing a trigger command. You may select (arm) only one trigger source at a time. The 3152B responds only to the selected trigger source, and ignores other sources. Use one of the following commands to select a trigger...
Page 66: Selecting The Trigger Level
Front-panel TRIG IN connector, TTLTrg lines 0 through 7, and ECLTrg line 0. Use the following command to select slope sensitivity for trigger events: This sets the 3152B to respond to positive trig:slop pos going transitions only. Positive transitions must cross the trigger level threshold to trigger a response.
Page 67: Using Trigger Delay
You may set the delay time in the range of 100 ns to 20 seconds in increments of 20 ns. The 3152B is programmable to drive or receive triggers on the Activating the VXIbus backplane trigger lines (TTLTrg0 through TTLTrg7). It is...
Page 68: Example: Generating Standard Waveforms
Previous paragraphs provided sinusoidal waveform examples, Example: showing how to set amplitude and offset. This section expands on Generating that capability, covering all nine standard waveforms in the 3152B internal library: sine, triangle, square, pulse, ramp, Gaussian Standard pulses, exponential pulses, DC, and noise.
Page 69: Generating Standard Waveforms
In a similar manner, you may use the Apply command with other standard waveforms to set some parameters while leaving others at their default values. Each standard waveform is built into the 3152B in a lookup table or Generating equation. Ten standard function shapes are available: Standard •...
Page 70 The reason for this variation is that even standard waveforms are in a manner similar to that of arbitrary waveforms, except that the 3152B stores standard waveforms in a permanent internal library for immediate use. At low frequencies, the number of points for each standard waveform is 1,000.

Page 76 This sets up the following conditions: 1) The next time you download data to the 3152B, it will go to the active segment (the 3152B will accept downloaded data only if a segment is designated as active).
Page 77: Selecting 12-Bit Or 16-Bit Waveform Resolution
12-bit data from legacy applications without the need to re- write the application program or data files. The default data resolution for the 3151B and 3152B is 12 bits. Other configurations, such as 3100M-3152B and 3100R-3152B, default to 16 bits. Regardless of the model number, you may set the...
Page 78: Changing The Sample Clock Frequency
Waveform interlace is changed to 2 (waveform size must divide by 2) • Vertical resolution of arbitrary waveforms is 12 bits (3152B has 16-bit resolution). The 3152B has Legacy Compatibility mode enabled by default. For Models 3100M and 3100R, Legacy Compatibility mode is disabled by default (the full 3152B specifications apply).
Page 79: Using The External Sample Clock Input
The 3152B does not have a single-tone sample clock source, but it provides a front-panel input, SCLK IN, that can accept a clock from an external source.

Page 81: Sequence Commands
It is possible to have only one link in a sequence, but the output will be a continuous waveform. If only one link is specified and the 3152B is placed in Triggered advance mode, then the output will behave as it would in Burst mode, where the repeat number replaces the burst count parameter.

Page 87 You can adjust the pulse characteristics only if all of its parameters can be adjusted both in the time and amplitude domain. The 3152B provides the necessary controls to do that. However, note that the pulse is generated digitally, and therefore has some limitations to observe.
Page 88: Pulse Design Limitations
Limitations 1. Step size determines resolution and period. The 3152B creates pulses digitally using a sample clock generator that clocks memory points. The rate of the sample clock defines the incremental resolution. For example, suppose you wish to generate pulses at a 100 ms pulse rate with 1 ms high time and the rest of the period low.

Page 231 \When using this method there is no need to define and download waveforms to individual segments. Using this command, segment table data is loaded to the 3152B using binary transfer like when downloading waveform data using the trace command. Binary transfer allows any 8-bit byte (including extended ASCII code) to be transmitted in a message.

Page 240: Sequenced Waveforms Control Commands
Sequenced waveforms are generated from waveforms stored in the 3152B as memory segments. Therefore, before a sequence can be used, download waveform segments to the arbitrary memory using TRAC# or block transfer methods. Information on how to partition the memory and how to download waveforms is given in Chapter 3 in the section titled Generating Arbitrary Waveforms.
Page 241: Table 5-8, Sequence Control Commands
Using this command, sequence table data is loaded into the 3152B using binary blocktransfer in a way similar to that of downloading waveform data using the trace command. Binary block transfer allows any 8-bit bytes (including extended ASCII code) to be transmitted in a message.

Page 254: Sweep Programming
Publication No. 980935 Rev. A 1. The number of bytes in a complete FM modulating waveform data must divide by 4. The 3152B has no control over data sent to its FM waveform during data transfer. Therefore, wrong data and/or incorrect number of bytes will cause errors 2.
Page 255 This specifies the sweep stop frequency. The 3152B normally sweeps from the start to the stop frequency, however, if the sweep direction is reversed, the 3152B will sweep from the stop to the start frequency. The start and stop frequencies may be programmed freely throughout the frequency range of the instrument.
Page 256 HS Syntax: 1600A<float>(?) Description This specifies the time that will take the 3152B to sweep from start to stop frequencies. The time does not depend on the sweep boundaries as it is automatically adjusted by the software to the required interval. At the end of the sweep cycle the output waveform maintains the sweep stop frequency setting except if the 3152B is in continuous run mode where the sweep repeats itself continuously.

Publication No. 980935 Rev. A 3152B will step through this list, outputting either carrier or shifted frequencies, depending on the data list: A Zero will generate the carrier frequency and a One will generate shifted frequency. Note that the waveform is always a sine wave and that the last cycle is always completed.

Page 263: Frequency Hopping Modulation Programming
The variable option lets you program different dwell times for each frequency hop. The 3152B output hops from one frequency to the next according to a sequence given in a hop table. The variable dwell time table contains dwell time data for each step, however, the fixed dwell time table does not contain any dwell time information and therefore, if you select the fixed option, make sure your dwell time is programmed as required.
Page 264 Below you can see how a hop table is constructed. The file sample below shows a list of 10 frequencies. The 3152B will hop through this list, outputting the next frequency each time it hops. Note that the carrier waveform is always sinewave and that the last cycle is always completed even if the dwell time is shorter than the period of the waveform.
