Using 6482 to output a trigger signal

Post by milosbasovic » August 6th, 2014, 10:24 am

Hello,

My apparatus is as follows: Keithley 6482, Pulse Generator, Power Supply of the Electron Gun, Electron gun itself, Sample connected to the channel of 6482.

My questions:
1) Can 6482 be used as an external trigger to activate pulse generator which will the send a signal to the Power Supply of the Electron Gun and store the measured current on the buffer of 6482?
2) If this is possible, can you give me directions on how to set up the trigger and buffer to record measurements.

Best Regards

1. Yes, the 6482 can be used to output a pulse.
In the trigger model(page 8-3) for the front panel the ARM layer can output a pulse or the TRIG layer can output a pulse any time after the SOURCE DELAY or SENSE phase.

2. To set it up to output a pulse in the ARM layer send the following command.
:ARM:OUTPUT TRIG
This will output a pulse when it leaves the ARM layer.
To set it up to output a pulse after the SOURCE , DELAY or SENS phase, then send one of the following commands.
:TRIG:OUTPUT SOURCE
:TRIG:OUTPUT DELAY
:TRIG:OUTPUT SENSE

The pulse is a TTL level negative going longer than 10usec pulse.
