Bit Function
15 to 9 ––––– Not used
8WTRIG
CH2
Waiting for Trigger. Indicates whether the instrument is waiting for a
trigger. This bit is set when CH 2 (in the case of dual-channel model)
is waiting for a trigger. Bit is reset when the waiting-for-trigger status is
canceled.
5WTRIG
CH1
Waiting for Trigger. Indicates whether the instrument is waiting for a
trigger. This bit is set when CH 1 (in the case of dual-channel model)
is waiting for a trigger. Bit is reset when the waiting-for-trigger status is
canceled.
4 ––––– Not used
3 SWE Sweep. Indicates whether the instrument is executing a frequency
sweep. This bit is set when a frequency sweep is being executed on
CH 1 or another channel (in the case of dual-channel model). Bit is
reset when the execution stops.
2 to 1 ––––– Not used
0 CAL Calibration. Indicates whether the instrument is being calibrated. This
bit is set when calibration is in progress and is reset when the
calibration is complete.
