Fluke PM-3384B, PM-3380B Peak-to-peak =, Sensitivity = 0.8 / 8 =, 100 mV/div, Trigger source =

COMMAND REFERENCE 4 - 89

After a *RST command, the peak-to-peak value is reset as follows:

-For channel 1 to 1.6V: vertical sensitivity = 200 mV/div.

-For channel 2 to 0.4V: vertical sensitivity = 50 mV/div.

-For channel 3 and 4 to 8V: vertical sensitivity = 1 V/div.

Note: If a 10:1 probe is connected to a channel, the peak-to-peak value is 10 times higher. For example, 80V instead of 8V.

Coupled values:

There exists a coupling between programming of the attenuator (vertical sensitivity) and the trigger level. If the attenuator is changed, the trigger level is also adapted to keep the signal display on the screen. Programming tip:

First program the attenuator (SENSe:VOLTage:RANGe:PTPeak), and then the trigger level (TRIGger:LEVel).

Limitations:

For the PM33x0B CombiScope instruments the peak-to-peak value of input channel 4 can only be set to 0.8V and 8V.

Example:
Send → *RST	Resets the instrument.
Send → SENSe:VOLTage2:RANGe:PTPeak 0.8	Peak-to-peak = 0.8V;
	sensitivity = 0.8 / 8 =
Send → TRIGger:SOURce INTernal2;LEVel .2	100 mV/div.
	Trigger source =
Send → SENSe:FUNCtion "XTIMe:VOLTage2"	channel 2; level = 0.2V.
	Switches channel 2 ON.
Send → INITiate:CONTinuous ON	Initiates continuous
	acquisitions.

Front panel compliance:

The SENSe:VOLTage<n>:RANGe:PTPeak command is the remote equivalent of the front panel AMPL "mV VAR V" keys.
