Command system EN Return format PN15, PN21, 01, or 10. Example SOURce1:MOD:BPSKey:DATA PN15 /* Set the data for channel 1 BPSK modulation to PN15 */ 3.5 BURSt subsystem This section introduces the BURSt subsystem. Burst mode has two burst modes, which are described below. The instrument enables one burst mode at a time. ⚫ Multi-period burst mode (default): Each time a trigger is received, the instrument will output a waveform for several periods (burst count). After outputting the specified number of periods, the instrument will stop and wait for the next trigger.
You can configure the instrument to initiate burst using internal triggers, or apply a trigger signal to Trig connector on the rear panel by pressing the [Trig Menu] key on the front panel, or send a software trigger command from a remote interface to provide ⚫ External gate controlled burst mode: The instrument output is in either the "on" or an external trigger source. "off" state depending on the external signal level applied to the TRIG connector on the rear panel. When this signal is true, the instrument will output a continuous waveform.
When this signal is false, the instrument will complete the current waveform period first and then stop and remain at the voltage corresponding to the initial burst phase of the waveform. 3.5.1 SOURce :BURSt:GATE:POLarity Command format SOURce :BURSt:GATE:POLarity NORMal|INVerted SOURce :BURSt:GATE:POLarity?
