4 - 116 COMMAND REFERENCE
Description:
The TRIGger:FILTer:HPASs:FREQuency command sets the MTB cutoff frequency
always at the fixed value of 30000 Hz (all values are rounded to 30 KHz).
The TRIGger:FILTer:HPASs:STATe command activates (ON) or deactivates
(OFF) the MTB high-pass filter.
Activating the MTB high-pass filter:
- automatically deactivates the MTB low-pass filter.
- sets the high-pass cutoff frequency at 30 KHz (HF-reject).
- sets the low-pass cutoff frequency at 0 Hz.
DeActivating the MTB low-pass filter:
- automatically activates the MTB low-pass filter.
- sets the high-pass cutoff frequency at bandwidth (60/100/200 MHz).
- sets the low-pass cutoff frequency at 0 Hz (DC coupling).
After a
*
RST command, the high-pass filter is OFF.
Note: The following coupling exists between programming the cutoff frequency
and (de)-activating the low-pass or high-pass filter:
Example:
Send
→ TRIGger:FILTer:HPASs:STATe ON Sets High-Pass filter on
(HF-reject).
Automatically switches
Low-Pass filter off.
Front panel compliance:
The TRIGger:FILTer:HPASs commands are the remote equivalent of the front
panel TRIGGER MAIN TB - ac, dc, lf-rej, hf-rej softkey menu.
