Hello,
I have a 53220A counter/timer, I want to measure the time interval between two channels, the way I want it to work is that the the channel1 should wait for a particular trigger than start the timer and when a particular trigger is reached at channel 2 the timer stops and also the counter stops i.e I need only one time interval measurement and not the continuous.
Now I am trying to read the manual and follow the instructions but its my first time using these devices so I am facing some difficulties. In particular I am having difficulties how to setup triggering and gating options, I want my channel 1 to start triggering and channel 2 to stop the measurement cycle. There are several triggering options, like internal external and manual.
So can any one help me with setting up my measurement cycle?
Thanks,

Below is the set up for the measurement:
Preset
Function: Time Interval 1-2
Channels 1 and 2:
Auto Level: Off
Start Channel Level: 500 mV (Ch. 1)
Stop Channel Level: 500 mV (Ch.2)
(Start and Stop) Slope: Pos
Coupling: AC
Impedance: 50
Range: 5V
You may need to experiment with the start and stop levels etc. for your particular signal. As you need to make only a one time measurement you can set the trigger source and readings per trigger as follows:
Trigger Source: Manual
Rdgs/Trigger: 1
Each time the trigger key is pressed a single time interval measurement is taken when the start and stop edges and levels are received. The counter’s gate time is not used as the start edge starts the measurement which continues until the stop edge is received.
One final item to consider is the measurement time out setting (Utility Instr Setup Time Out Settings). This value should be longer than the expected time interval so that the measurement completes before the time out occurs.
To save some typing, attached is a counter state file with the settings listed above (including a 2s time out). Extract the state file from the zip file. To load the state, store the extracted state file (STATE_TI.sta) on a USB thumb drive and insert the thumb drive on the front panel of the counter. Press the following keys:
Utility Store/Recall Recall State
Using the knob on the front panel, highlight the state file (STATE_TI.sta) and then press ‘Select’.
Good luck.
