FREQuency in Hz.
TRAN:FREQ? MAX and TRAN:FREQ? MIN? return the
maximum and minimum programmable frequency values.

TRAN:MODE Channel-Specific Transient Command/Query
Description
Selects the type of operation provided by the transient generator for each channel.
■ CONTinous mode provides periodic pulses of programmable frequency and duty
cycle, which are not related to TWIDth in any way. Each channel has its own
oscillator that runs asynchronously with respect to oscillators of other channels.
■ PULSe mode provides a triggered one-shot pulse with a programmable pulse
duration. When a trigger occurs, the input goes to TLEVel for the duration of
TWlDth (which is not related to FREQuency or DCYCle in any way) and then
returns to LEVel. This mode is not retriggerable; triggers that occur while the input is
at TLEVel are ignored. In multiple electronic loads, the trigger is applied to all
channels simultaneously and TRIG:SOUR TIMer can be used to produce
synchronized load waveforms (See TRIGer Subsystem).
■ TOGGle mode causes the input to switch between LEVel and TLEVel on alternate
triggers. Odd triggers set TLEV; even triggers set LEV, FREQ, DCYC, and TWID
have no effect on this mode. Triggers are applied to all channels simultaneously in the
multiple electronic load.
Note
The Operation Status Condition register WTG bit (See Chapter 5 - Status Reporting) is
not affected by setting either the PULSe or TOGGle modes.
