Page 29: Acquisition And Setup
® Acquisition and Setup R&S Basics 2 Acquisition and Setup This chapter describes the horizontal and vertical settings as well as the acquisition and probe setup. 2.1 Basics This chapter provides background information on the essential settings in the vertical and horizontal systems, on acquisition setup and probing.
Page 30 Basics Fig. 2-1: Input range and resolution of the ADC With R&S RTO, you can work with multiple diagrams, and each diagram obtains the full vertical resolution, no matter where the diagram is placed. Therefore, use a separate diagram for each waveform instead of the traditional setup that arranges the waveforms side by side in one diagram.
Page 31: Sampling And Acquisition
® Acquisition and Setup R&S Basics Fig. 2-3: R&S RTO setup of multiple waveforms in separate diagrams: best resolution 2.1.1.3 Bandwidth For analog applications the highest signal frequency determines the required oscillo- scope bandwidth. The oscilloscope bandwidth should be slightly higher than the maxi- mum frequency included in the analog test signal to measure the amplitude with very little measurement error.
Page 32 - either channel 1 or channel 2, and either channel 3 or 4. Using a channel on R&S RTO oscilloscopes is more than displaying it. In the background, without displaying the channel, it can serve as trigger source, as source of a math wave- form, cursor or automatic measurement.
Page 33 The R&S RTO provides the following acquisition features: ● You can combine resolution enhancement and waveform decimation modes with waveform arithmetic.
Page 34 Acquisition and Setup R&S Basics 2.1.2.3 Acquisition Control You can run the R&S RTO in two ways: ● Continuous: the instrument acquires data until you stop it manually. ● NxSingle: the instrument samples and processes a specified number of acquisitions.
Page 35: Horizontal System
® Acquisition and Setup R&S Basics 2.1.3 Horizontal System 2.1.3.1 Parameters of the Horizontal System The control parameters of the horizontal system are tightly connected. Thus, changing one parameter affects the other parameters as well. The mathematical dependencies can be summarized as follows: The time scale can be changed, all other parameters are adjusted automatically.
Page 36: Probes
® Acquisition and Setup R&S Basics Two parameters set the position of the horizontal acquisition window in relation to the trigger point: reference point (time reference) and trigger offset. With these parameters you choose the part of the waveform you want to see: around the trigger, before, or after the trigger.

Page 40: Setting Up The Waveform
® Acquisition and Setup R&S Setting Up the Waveform 2.2 Setting Up the Waveform This chapter contains the fundamental procedures for setting up the acquisition and adjusting the channel waveforms. 2.2.1 Setting Up the Signal Input with Autoset Autoset is the solution for the major part of routine test-setup. It is also a good start if you need to use more complex trigger settings.
Page 41: Starting And Stopping Acquisition
® Acquisition and Setup R&S Setting Up the Waveform 2. Select the "Enhancement". If "Interpolated time" is set, select also the "Interpolation mode". Enhancement affects all waveforms of all channels. The instrument uses enhance- ment settings if the "ADC sample rate" is less than the "Sample rate"; otherwise these settings are ignored.

Page 48 ® Acquisition and Setup R&S Reference for Acquisition and Setup Channel-dependent settings The "Decimation" and "Wfm arithmetic" are specific for each waveform. Make sure to select the channel tab first, then set up the waveforms. Resolution enhancement If the ADC sample rate is too slow to capture sufficient samples to achieve the required resolution, the sample rate can be increased by adding calculated points to the waveform record.
Page 49 After a number of acquisitions, the oscilloscope builds the waveform from the sampled points. The R&S RTO uses the sequential equivalent-time sampling method. When a trigger occurs, a sample is taken after a very short delay time.
Page 50 Decimation reduces the data stream of the ADC to a stream of waveform points with lower sample rate and a less precise time resolution. The R&S RTO uses decimation, if the waveform "Sample rate" is less than the "ADC sample rate". In this case, enhance- ment settings are ignored.

Current probes are not recognized automatically but the parameters of R&S current probes (R&S RT-ZCxx) are known to the instrument. On the "Manual" mini-tab, select the probe type with "Predefined probe".
Page 62 ® Acquisition and Setup R&S Reference for Acquisition and Setup Auto Zero, AutoZero DC offset, Use AutoZero Differences in DUT and oscilloscope ground levels may cause larger zero errors affecting the waveform. If the DUT is ground-referenced, the Auto Zero function corrects the zero error of the probe to optimize measurement results at small signal levels.The validation limit depends on the probe attenuation because probes with high attenation often have to compensate high offsets.

Page 70 External trigger input, analog and digital trigger system In R&S RTO, the trigger types use either an analog or a digitized signal as the trigger signal. If the trigger source is a channel input, the trigger types use a digitized signal. The trigger system of the instrument is a separate system, thus the signal processing by enhance- ment, decimation and arithmetic has no impact on the trigger signal.

Page 212: Configuring Fft Waveforms
® Mathematics R&S FFT Analysis 6.3.2 Configuring FFT Waveforms During FFT analysis, a signal in the time domain is converted to a spectrum of frequen- cies. A basic FFT waveform can be displayed very quickly. By defining additional FFT parameters, the waveform can be configured in more detail. As a result, either the magnitude or the phase of the determined frequencies can be displayed, or more complex FFT functions.

The resolution bandwidth defines how precise the results are, i.e. how close together the individual frequencies can be. Small values result in a high precision, as the distance between two distinguishable frequencies is small. Higher values decrease the precision, but increase performance.

Page 422 ® Remote Control R&S Basics 16.1.6.1 Structure of a SCPI Status Register Each standard SCPI register consists of 5 parts. Each part has a width of 16 bits and has different functions. The individual bits are independent of each other, i.e. each hardware status is assigned a bit number which is valid for all five parts.
Page 423 ® Remote Control R&S Basics This part can be written into and read as required. Its contents are not affected by reading. ● EVENt The EVENt part indicates whether an event has occurred since the last reading, it is the "memory" of the condition part. It only indicates events passed on by the transition filters.
Page 424 ® Remote Control R&S Basics Fig. 16-2: Overview of the status registers hierarchy ● STB, SRE The STatus Byte (STB) register and its associated mask register Service Request Enable (SRE) form the highest level of the status reporting system. The STB provides a rough overview of the instrument status, collecting the information of the lower-level registers.
Page 425 ® Remote Control R&S Basics The IST flag ("Individual STatus"), like the SRQ, combines the entire instrument status in a single bit. The PPE fulfills the same function for the IST flag as the SRE for the service request. ● Output buffer The output buffer contains the messages the instrument returns to the controller.
Page 426 ® Remote Control R&S Basics Bit No. Meaning MAV bit (message available) The bit is set if a message is available in the output buffer which can be read. This bit can be used to enable data to be automatically read from the instrument to the controller. ESB bit Sum bit of the event status register.
Page 427 ® Remote Control R&S Basics Bit No. Meaning Device-dependent Error This bit is set if a device-dependent error occurs. An error message with a number between -300 and -399 or a positive error number, which denotes the error in greater detail, is entered into the error queue.
Page 428 ® Remote Control R&S Basics Fig. 16-3: Overview of the STATus:QUEStionable register Table 16-6: Bits in the STATus:QUEStionable register Bit No. Meaning 0 to 2 not used COVerload This bit is set if a questionable channel overload occurs (see "...
Page 429 ® Remote Control R&S Basics Bit No. Meaning NOALigndata This bit is set if no alignment data is available - the instrument is uncalibrated. LIMit This bit is set if a limit value is violated (see " STATus:QUEStionable:LIMit, STATus:QUEStiona- ble:MARGin, STATus:QUEStionable:LAMP registers"...
Page 430 ® Remote Control R&S Basics or additional measurement of assigned measurement are violated. The LAMP (Low AMPlitude) bit is set if the magnitude of the signal is too low to get reliable measurement results. Table 16-9: Bits in the STATus:QUEStionable:LIMit, STATus:QUEStionable.MARGin, and STA- Tus:QUEStionable:AMP registers Bit No.
Page 431 ® Remote Control R&S Basics ● Query of a specific instrument status by means of commands ● Query of the error queue Service Request Under certain circumstances, the instrument can send a service request (SRQ) to the controller. Usually this service request initiates an interrupt at the controller, to which the control program can react appropriately.
Page 432 ® Remote Control R&S Basics Query of an instrument status Each part of any status register can be read using queries. There are two types of com- mands: ● The common commands *ESR?, *IDN?, *IST?, *STB? query the higher-level reg- isters.
