Fluke PM-3394B Filter, Frequency LOW-PASS on HIGH-PASS on, Sets cutoff frequency = 30 KHz

4 - 118 COMMAND REFERENCE

Description:

The TRIGger:FILTer:LPASs:FREQuency command sets the MTB cutoff frequency, which defines the trigger coupling. The specified frequency values are rounded as follows:

- 0 .. 4.99 is rounded to 0 Hz, i.e., DC coupling.

-5 .. 4999.99 is rounded to 10 Hz, i.e., AC coupling.

-Š15000 is rounded to 30 KHz, i.e., LF-reject.

The TRIGger:FILTer:LPASs:STATe command activates (ON) or deactivates (OFF) the MTB low-pass filter.

Activating the MTB low-pass filter:

-automatically deactivates the MTB high-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).

DeActivating the MTB low-pass filter:

-automatically activates the MTB high-pass filter.

-sets the high-pass cutoff frequency at 30 KHz.

-sets the low-pass cutoff frequency at 0 Hz.

After a *RST command, the low-pass filter is ON and the cutoff frequency is 0 Hz (DC coupling).

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:LPASs:STATe ON

Sets Low-Pass filter on + cutoff frequency = 0 Hz (DC coupling). Automatically switches High-Pass filter off.

Send → TRIGger:FILTer:LPASs:FREQuency 3E+4

‘	Sets cutoff frequency = 30 KHz
	(LF-reject).

The TRIGger:FILTer:LPASs commands are the remote equivalent of the front panel TRIGGER MAIN TB - ac, dc, lf-rej, hf-rej softkey menu.
