Page 13: Learning Gpib Remote Control Basics
The General Purpose Interface Bus ( ) is used for remote gpib control of the 4396B Network/Spectrum/Impedance Analyzer (analyzer). GPIB is a standard for interfacing instruments to computers and peripherals. This standard supports worldwide standards IEEE 488.1, IEC-625, and IEEE 488.2. The GPIB interface allows the analyzer to be controlled by an external computer.
Page 14: To Prepare For Gpib Control
If you are using only Instrument BASIC and no external controller, prepare the analyzer for your use. For details, see Using Instrument BASIC with the 4396B If you are using a computer as an external controller, a. Set the analyzer to addressable only mode.
Page 15 How large a system A maximum of 15 devices can be connected on one bus system. can you congure? The length of cable between one device and another must be less than or equal to four meters. The total length of cable in one bus system must be less than or equal to two meters times the number of devices connected on the bus (the GPIB controller counts as one device).
Page 16: Gpib Commands Introduction
GPIB Commands Introduction All the analyzer's front-panel keys have a corresponding GPIB command. By executing an GPIB command, you can operate the analyzer as if you were pressing the corresponding key. For example, Pressing is the same as executing the GPIB command, Preset Note Each of the analyzer's functions has two corresponding GPIB commands:...
Page 17: To Program A Basic Measurement
To Program a Basic Measurement This section describes how to organize the commands into a measurement sequence. Figure 1-2 shows a typical program ow for a measurement. Figure 1-2. Program Flow The following program performs the measurement ow controlling the analyzer using GPIB. This guide shows program lists of sample programs for an external controller.

Lines 60 and 70 perform the same operation as pressing NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN Preset...
Page 19: Perform Calibration
In lines 80 to 110 (setting frequency), parameters are required with the GPIB command. To set parameters, see \To Execute an GPIB Command with a Parameter" later in this chapter. Perform Calibration In lines 140 to 240, the GPIB program follows the key strokes required to calibrate from the front panel.
Page 20: Post-Processing
Post-Processing Line 380 activates the marker and line 390 moves the marker to the maximum value on the trace. For details on using the marker, see Chapter 4. Transfer Data Line 400 the measured data is transferred to the controller. For details about data transfer, see Chapter 4.
Page 21: Triggering The Analyzer From Remote
Triggering the Analyzer from Remote This chapter describes how to control the trigger system of the analyzer. To trigger a measurement from a controller, the following steps are commonly used: 1. Set the trigger source to: Bus, or Internal (free run) (In External, Video, Manual or Gate trigger, you cannot trigger from the controller, so these sources are not mentioned in this guide.) 2.
Page 22: To Measure Continuously
In Figure 2-1, 1. After a GPIB command execution, the analyzer returns to the \Idle" state. 2. By setting the number of measurements, the analyzer changes from the \Idle" state to the \Waiting for Trigger" state. 3. At the \Waiting for Trigger" state, a trigger input (corresponding to the trigger source) starts a measurement.
Page 23: To Trigger A Measurement From The Controller
What can you do to Send the command: abort a measurement? The measurement sweep is aborted. What are other trigger Instead of , you can use, commands? for single measurement parameter for number of group measurements When you transfer measurement data to the controller, you must use either the command to synchronize the controller and the analyzer.

Page 25: Synchronizing The Analyzer From Remote
Synchronizing the Analyzer from Remote GPIB analyzer control programs that can be used for guiding you through an analyzer calibration, and for reading and manipulating measurement data. The control program must wait until the calculation data is processed before continuing with the next instruction.
Page 26: To Wait For The Preceding Operation To Complete
To W ait For the Preceding Operation to Complete Figure 3-2. Sample Program: To Wait for the Preceding Operation to Complete Let Controller Wait For Operation to Complete (OPC) In line 80, the command waits for the preceding operations to complete and then returns In line 90, the controller pauses the program until the analyzer returns a .
Page 27: To Wait For Sweep End
To W ait for Sweep End Figure 3-3. Sample Program : To Wait for Sweep End Enable Sweep-End Bit Line 60 clears all bits of the Status Registers and the Enable Registers. In line 70, the command sets the Service Request Enable Register to 00000100 (this enables bit 2 of the Status Byte Register).
Page 28: Enable Srq Interrupt
Enable Registers select which events in the analyzer can cause a service request (SRQ). By setting bit 0 of the Event Status Enable Register B to 1, the occurrence of the corresponding event (sweep-end) sets bit 0 of the Event Status Register B. When this bit is set (and is enabled), it is used to set a summary bit in the Status Byte Register (bit 2).
Page 29: To Report Command Error Occurrence
To Report Command Error Occurrence Figure 3-5. Sample Program : To Report Command Error Occurrence For details on SRQ interrupt, see the \To Wait for Sweep End" example. Enable Error Bit Line 70 clears all bits of the Status Registers and Enable Registers. In line 80, the command sets the Service Request Enable Register to 00100000 (this enables bit 5 of the Status Byte Register).
Page 30: Report Command Error
Figure 3-6. Command-Error Bit Enabling Report Command Error If an GPIB command (executed between lines 100 and 160) causes an GPIB command error, the analyzer generates an SRQ and the controller branches to . For example, the statement: Setting center frequency, but no parameter causes an SRQ interrupt and branch to Output Error These commands retrieve the error number and description.
Page 31: Return To Execute Gpib Command
Return to Execute GPIB command Lines 230 to 270 clear SRQ before returning to the main routine. Line 230 reads the analyzer's status byte. The statement reads the Status Byte Register of the address (analyzer), and enters the value into . The command error causes the SRQ and with bit 5 and bit 6 of the Status Byte Register set, the value of is 96.
Page 33: Reading Measurement Data
Reading Measurement Data This chapter describes how to read measurement data over the GPIB. Measurement data can be read out of the analyzer in the following ways: 1. Data can be read o the trace selectively using the markers. The present value of the marker (real-imaginary data and sweep parameter) is retrieved. For additional information on the marker functions, see the Function Reference 2.

Page 36: To Get Measurement Trace Using Ascii Format
To Get Measurement Trace Using ASCII Format Figure 4-2. Sample Program : To Get Measurement Trace Using ASCII Format Set the Receive Array Line 180 sets the array size to the analyzer's maximum number of measurement points (801). In this example, it is assumed that the analyzer is in the network analyzer mode of operation, in which each point has complex data.
Page 37: Set Data Transfer Format
Set Data Transfer Format Line 190 tells the analyzer to use the ASCII transfer format. Read Data retrieves DATA TRACE ARRAYS, and retrieves sweep parameters. In line 210 and 230, you must choose to allow for an insucient number of data points to ll the array (which is 801 as declared in line 180).

Page 39: Set The Receive Array
Figure 4-3. Sample Program : To Get Measurement Trace Using IEEE 64-bit Floating Point Format (For External Controller) (2/2) This program is similar to the ASCII transfer program. However, you must set the data transfer format OFF when using the binary data transfer format. Set the Receive Array Line 190 sets the array size to the analyzer's maximum number of measurement points (801).
Page 40: Read Data
Read Data FORM3 has an eight-byte header to deal with. The rst two bytes are the ASCII characters #6. This indicates that a xed length block transfer follows and that the next 6 bytes form an integer specifying the number of bytes in the block to follow. The header must be read in so that data order is maintained (lines 260 and 300).
Page 41: Set The Receive Array
Before running the program in Figure 4-5, you must modify the dimension of the data arrays to match the analyzer type (network or spectrum). (See the \Set the Receive Array" below.) Figure 4-5. Sample Program : To Get Measurement Trace Using IEEE 64-bit Floating Point Format (For Instrument BASIC) Set the Receive Array Line 190 sets the array size to the maximum number of data.
Page 42: Set Data Transfer Format
If the number of measurement points change, then so does the number of data. Instrument BASIC allows for insucient data in lines 220 to 270 (see \Read Data"). Set Data Transfer Format To use FORM3 the computer must be instructed to stop formatting the incoming data with the statement.
Page 43: Writing Data Arrays To The Analyzer

Each point on the graphics screen is addressable using a coordinate address as shown in Figure 7-1. The bottom left corner is the origin (0,0) and the top right corner is the maximum horizontal and vertical end points (393,299). The MOVE and DRAW statement parameters are specied using these coordinate values.
Page 141: Using The External Run/Cont Connector
Using the External RUN/CONT Connector You can use the RUN or CONT commands in a program by inputting a TTL-compatible signal to the External RUN/CONT connector on the rear panel. At the negative-going edge of a pulse more than 20 s wide (T ) in the LOW state will trigger RUN or CONT.
Page 142: Using The I/O Port In Basic Programs
Using the I/O Port in BASIC Programs The Instrument BASIC can directly control the I/O port without using GPIB commands. This is faster than using the GPIB commands. Reads the 4-bit data from the I/O Port and returns a decimal value. Outputs the decimal value of the 8-bit data to the OUT 0 to 7 lines of data the I/O port.
Page 143: Special Features And Advanced Techniques
Special Features and Advanced Techniques The topics covered in this chapter are : Autoloading and running a program automatically (AUTOST) On Key Label function Increasing program speed Autoloading and Running a Program Automatically (AUTOST) The analyzer allows you to create a special program le called AUTOST. This program is automatically loaded and run every time the analyzer is turned ON.
Page 144: Increasing Program Speed
Increasing Program Speed Because the analyzer's CPU interleaves processing measurements and executing a program, program execution speed depends on the measurement conditions. The display process also requires processing time. To increase program speed (increase throughput), set the analyzer to the following conditions: If you do not need to measure the when executing a program, set TRIGGER MODE to HOLD.
