During operations such as sweep, FSK, FM, and other modulation modes, the 3152B quickly synthesizes the modulated waveform using the DDS circuit. The variety of modulated waveforms are described below. The 3152B can sweep the output frequency between minimum and maximum values that you specify.
3152B User Manual Publication No. 980935 Rev. M AM The AM function modulates the amplitude of the 3152B output waveform. Four standard modulating waveforms are available: sine, triangle, square, and ramp. AM can be used in Continuous, Triggered, and Gated modes. Modulation depth is programmable from 0% to 100% and up to 200% in some cases. Frequency Hopping The Frequency Hopping function causes the output frequency to hop through a sequence of frequencies.
Publication No. 980935 Rev. M 3D Digital Pulse Waveforms 3152B User Manual The 3D function allows you to sweep the output in three dimensions at the same time: frequency, amplitude, and phase. You may operate the 3D function only from the ArbConnection utility. The waveform memory of the 3152B can be programmed as if it were a pulse generator.

3152B User Manual Publication No. 980935 Rev. M trig:sour ttlt trig:sour bus Selecting the Trigger Level internal trigger generator must be larger than the period of the waveform. This selects and activates one or more of the VXIbus backplane triggers (TTLTrg0 through TTLTrg7) as the active source for trigger events. If more than one input is activated, the instrument will accept trigger events from all active trigger lines.
Publication No. 980935 Rev. M Using Trigger Delay 3152B User Manual The trigger delay value designates the time that will elapse from a trigger event to the start of the waveform at the output connector. The trigger delay adds to the system delay time (see the definition of System Delay in Appendix A). Therefore, when delaying the trigger, always consider the added factor of the system delay.
3152B User Manual Example: Generating Standard Waveforms Publication No. 980935 Rev. M Previous paragraphs provided sinusoidal waveform examples, showing how to set amplitude and offset. This section expands on that capability, covering all nine standard waveforms in the 3152B internal library: sine, triangle, square, pulse, ramp, Gaussian pulses, exponential pulses, DC, and noise.

Selects the standard square wave as the active function, and simultaneously sets the frequency to 10.7 MHz (10.7e6), amplitude to 2 V, offset to 1 V, and duty cycle to 30%. Turns on the output. The above is an example of a full utilization of the Apply command, including the frequency, amplitude, offset, and duty cycle parameters for a standard square wave.
Publication No. 980935 Rev. M What Are Arbitrary Waveforms? 3152B User Manual Arbitrary waveforms are generated from digital data points which are stored in memory. Each data point (waveform sample) has a vertical resolution of 16 bits (65,536 levels). Another way to express this is that each sample has an amplitude resolution of one part in 65,536. For legacy emulation, 12 bit waveform data is converted into 16 bit data with a four position shift.
3152B User Manual Publication No. 980935 Rev. M Figure 3-1, ArbConnection Example of a Complex Waveform Memory Management Commands Creating Memory Segments Segments are defined using the following command: trac:def 1,2000 Defines segment #1 as having 2,000 sample points. Any waveform downloaded to this segment must have exactly 2,000 data points. This command has two variables: segment number and segment size. Note that numbers, not names, are assigned to segments.
Publication No. 980935 Rev. M 3152B User Manual You may use the above command to create as many segments as required. However, if you have many segments, it is more efficient to combine all segments into a single waveform, and then create a memory partition table for the individual waveform segments. To do this, use the following command: segm Downloads the entire memory partition table to the instrument in one operation. Chapter 5 provides details on the use of this command.
3152B User Manual Loading Arbitrary Waveforms Publication No. 980935 Rev. M The easiest way to download waveforms to the 3152B is with ArbConnection. Using this application, you may define, create, and download memory segments to the 3152B. For maximum flexibility, you may download waveforms to the 3152B from your own program.
Publication No. 980935 Rev. M 3152B User Manual middle of the sequence and not with the first segment. Use the following command to select an active segment: trac:sel Selects the active segment .

M 3152B User Manual Chapter 5 Programming Reference What’s in This Chapter This Chapter lists and describes the set of SCPI-compatible (Standard Commands for Programmable Instruments) remote commands used to operate the 3152B. To provide familiar formatting for users who have previously used the SCPI reference documentation, the command descriptions are dealt with in a similar manner.
3152B User Manual Publication No. 980935 Rev. M [:STATe] OFF | ON OUTPut is the root keyword of the command; FILTer and STATe are second level keywords. LPASs is third level keyword. A colon ( : ) separates a command keyword from a lower level keyword. Command Format The format used to show commands in this manual is shown below: FREQuency {|MINimum|MAXimum} The command syntax shows most commands (and some parameters) as a mixture of upper and lowercase letters.
3152B User Manual Publication No. 980935 Rev. M Parameters commands. For example, consider the following command: FREQuency {|MINimum|MAXimum} Instead of selecting a specific frequency, substitute MIN to set the frequency to its minimum value or MAX to set the frequency to its maximum value. Querying Parameter Setting Query the current value of most parameters by adding a question mark ( ? ) to the command.
3152B User Manual Publication No. 980935 Rev. M decimal points, and scientific notation. Special values for numeric parameters like MINimum and MAXimum are also accepted. Engineering unit suffixes with numeric parameters (e.g., MHz or kHz) can also be sent.
