4 Remote Interface Reference
234 Keysight 33210A User’s Guide
BURSt:STATe {OFF|ON}
BURSt:STATe?
Disable or enable the burst mode. To avoid multiple waveform changes, you can
enable the burst mode after you have set up the other burst parameters.
The default is OFF. The :STAT? query returns “0” (OFF) or “1” (ON).
– The function generator will not allow the burst mode to be enabled at the
same time that sweep or any modulation mode is enabled. When you enable
burst, the sweep or modulation mode is turned off.
UNIT:ANGLe {DEGree|RADian}
UNIT:ANGLe?
Select degrees or radians to set the starting phase for the burst with the
BURS:PHAS command (remote interface only). The default is DEG.
The :ANGL? query returns “DEG” or “RAD”.
–
From the front panel, the starting phase is always displayed in degrees
(radians
are not available). If you set the starting phase in radians from the remote
interface and then return to front-panel operation, you will see that the
function generator converts the phase to degrees.
TRIGger:SOURce {IMMediate|EXTernal|BUS}
TRIGger:SOURce?
Select the trigger source for the triggered burst mode only. In the triggered burst
mode, the function generator outputs a waveform with the specified number of
cycles (burst count) each time a trigger is received. After the specified number of
cycles have been output, the function generator stops and waits for the next
trigger. The default is IMM. The :SOUR? query returns “IMM,” “EXT”, or “BUS”.
–
When the
Immediate
(internal) source is selected, the frequency
at which the
burst is generated is determined by the burst period (BURS:INT:PER
command).
–When the External source is selected, the function generator will accept a
hardware trigger applied to the rear-panel Trig In connector. The function
generator outputs the specified number of cycles each time Trig In receives a
TTL pulse with the edge polarity specified by the TRIG:SLOP command (see
page 235). External trigger signals that occur during a burst are ignored.
