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 =
100 mV/div.
Send
→ TRIGger:SOURce INTernal2;LEVel .2 Trigger source =
channel 2; level = 0.2V.
Send
→ SENSe:FUNCtion "XTIMe:VOLTage2" 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.
