- Trigger Source
- The 3152B accepts triggers from a number of sources: Bus, VXI Backplane (TTL Trigger 0 through 7 and ECL Trigger 1), External, and Internal. The VXI backplane trigger lines can synchronize operation with other devices residing in the VXIbus chassis.
- The various trigger source options are:
- Trigger Parameters
- Gated Mode: There are two modes that define how the 3152B will gate. The standard mode is Level, in which a selectable level (high or low) on the trigger signal enables the output. The other mode is Transition, in which each transition toggles the gate on or off. The level or transition direction is programmable using the Slope options.
- Slope: If you click on “Pos”, the instrument triggers on the positive-going (rising) edge of the trigger signal. Similarly, if you click on “Neg”, the instrument will trigger on the negative-going (falling) edge of the trigger signal. Note that this affects only the signals that are accepted from the front panel trigger input.
- Burst: Programs the burst counter for burst mode. Once triggered, the 3152B outputs a series of output waveforms that ends when the burst counter reaches the specified count.
- Trigger Level: Programs the trigger level parameter. Depending on the slope setting, the 3152B will be triggered to output waveforms when the trigger level threshold has been crossed.
- Manual Trigger
- The TRIG button operates only in conjunction with the BUS mode. Press the TRIG button to trigger the instrument as if an external trigger has been applied.

- FM Parameters
- Baseline – The Baseline parameter affects the output characteristics in one of the interrupted run modes (i.e., triggered, burst). In this case this parameter defines where the signal idles between triggers. There are two options: CW and DC. The DC option will set the idle state to a DC level, meaning that in between triggers, the output resides on a DC level and generates modulation when a trigger is accepted. The CW is similar except the signal idles on the pre-trigger CW frequency setting, executes the modulation upon receipt of a legal trigger signal and returns to continuous CW frequency output.
- Standard FM Parameters - These parameters are active only when one of the built-in waveforms is selected as the modulating signal. These are: Sine, Triangle, Square, or Ramp. The modulation frequency, deviation and marker frequency control the standard FM modulation scheme.
- Modulating Wave - Defines the shape of the modulating waveform. There are two basic options: Standard (built-in) waveforms and Arbitrary waveforms. If you do not need exotic waveforms, you can use one of the built-in standard wave shapes: Sine, Triangle, Square, or Ramp. These waveforms can be adjusted for their frequency and deviation range. On the other hand, you can select the arbitrary modulating wave option where you can use any shape, although you must load the modulating waveform from an external application, such as the FM composer in ArbConnection. Information on the standard and arbitrary FM functions is given in Chapter 3. Click on the button next to the required modulating waveform shape to select it.
- Arbitrary FM Parameters – Allow adjustment of the sample clock of the modulating waveform. These parameters are active only when arbitrary modulating waveform option is selected. The modulating waveform must be downloaded from an external utility such as ArbConnection and the sample clock is programmed from this location.

- CW Frequency –The CW Frequency is the frequency of the carrier waveform.
- Baseline – The Baseline parameter affects the output characteristics in one of the interrupted run modes (i.e., triggered, burst). In this case this parameter defines where the signal idles between triggers. There are two options: CW and DC. The DC option will set the idle state to a DC level, meaning that in between triggers, the output resides on a DC level and generates modulation when a trigger is accepted. The CW is similar except the signal idles on the pre-trigger CW frequency setting, executes the modulation upon receipt of a legal trigger signal and returns to continuous CW frequency output.
- Modulating Wave – Defines the shape of the modulating waveform. There are four built-in standard wave shapes: Sine, Triangle, Square, or Ramp. These waveforms can be adjusted for their frequency and deviation range. Click on the button next to the required modulating waveform shape to select it. The modulating waveform can be selected independently for each channel
- Freq – Programs the frequency of the modulating waveform. Note that the frequency setting must be smaller than the CW frequency for the AM function to operate correctly. Note that the modulating frequency setting is common to both channels.
- Depth – The Depth parameter programs the modulation depth, or index in percent of the un-modulated CW amplitude. The depth is symmetrical about the center of the CW amplitude. Each channel can have a unique setting of the modulation depth.

- Sweep Parameters
- Baseline – The Baseline parameter affects the output characteristics in one of the interrupted run modes (i.e., triggered, burst). In this case this parameter defines where the signal idles between triggers. There are two options: CW and DC. The DC option will set the idle state to a DC level, meaning that in between triggers, the output resides on a DC level and generates modulation when a trigger is accepted. The CW is similar except the signal idles on the pre-trigger CW frequency setting, executes the modulation upon receipt of a legal trigger signal and returns to continuous CW frequency output. Note that in sweep modulation, the Start parameter replaces the CW value.

- FSK
- Control Data – The Control Data button in the FSK group provides access to the data string that controls the sequence of base frequency and shifted frequency. It contains the list of “0” and “1” values that the output will repeatedly follow for its frequency shift keying sequence advance as programmed.
- “0/1” Frequency – In FSK, the carrier waveform (CW) has two frequencies: an initial frequency level which is set by the “0” frequency parameter and shifted frequency which is set by the “1” frequency. The control data table has a list of “0” and “1” values that flag when the frequency shifts from base to shifted frequency.
- Baud – The baud parameter sets the rate at which the generator steps through the sequence of the FSK Control Data bits.
- Marker Index – The marker index programs a step in the control data string to output a pulse at the SYNC output connector. The SYNC State button must be turned on to generate the FSK marker output.
- PSK

The CW is similar except the signal idles on the pre-trigger CW frequency setting, executes the modulation upon receipt of a legal trigger signal and returns to continuous CW frequency output.
- Amplitude Hop
- Hop Data – The Hop Data button in the Ampl Hop group provides access to the data string that controls the sequence of amplitude hops. The hop data table contains a list of amplitude levels that the output steps through the amplitude levels of as programmed in the hop data table.
- Variable Hold – The Variable Hold parameter determines how long each step of amplitude dwells before stepping to the next amplitude setting. By selecting Variable Hold, the hold time changes automatically from one step to the next depending on the hold time value that is affixed to the hop step. The values can be programmed in the HOP Data table.
- Dwell Time –The Dwell Time parameter programs the period of time that must elapse before the output amplitude hops to the next amplitude setting. Dwell Time is associated with the Fixed Dwell option only.
- Marker Index – The marker index programs a step in the hop data string to output a pulse at the SYNC output connector. The SYNC State button must be turned on to generate the hop marker output.
- Frequency Hop
- Hop Data – The hop data button in the frequency hop group provides access to the data string that controls the sequence of frequency hops. The hop data table contains a list of frequencies and the output will step from one frequency level to another in the same order as programmed in the hop data table.
