Fluke PM-3390B, PM-3380B Filter Frequency LOW-PASS on HIGH-PASS on, Automatically switches

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:

				FILTER
	FREQUENCY		LOW-PASS ON		HIGH-PASS ON
0		Hz	DC coupling		HF-reject
10		Hz	AC coupling		HF-reject
30		KHz	LF-reject		HF-reject
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.
