Using EPOCH to Control Start of Reading Capture
Objective/Actions
Note
In Epoch mode, the trigger subsystem is switched to Initiate
Continuous On at the start of the Epoch (equivalent to
sending INIT:CONT ON). In this example the Epoch expires
1 second after start (equivalent to sending INIT:CONT OFF).
The three day timing is controlled in one of the ARM layers.
To use the Epoch mode to start taking groups of 50 readings spaced at 30 second intervals
starting on the hour every hour for 3 days enter the commands below.
Example
Result/Comments
:TRIGger:RESet
Reset the trigger system to defaults
:INITiate:EPOCh:STARt
2022,11,30,00,00,00
Start the sequence
:INITiate:EPOCh:STOP:
2022,11,30,00,00,01
1 second later
:ARM1:TIMer 3600
Arm every 1 hour
:ARM1:COUNT 72
ARM 72 times - process runs for 72 hours
:TRIGGER:SOURce TIMer
:TRIGGER:COUNT 50
Take 50 readings for each ARM event
:TRIGGER:TIMer 30
30 seconds between each of the 50 readings
:TRIGger:DELay:AUTO OFF
Turn auto delay off
:TRIGGER:DELay 0
Set Delay to 0.000
Compare Two Resistance Values using SCAN
Objective/Actions
To compare two resistances using SCAN:
1. Connect two resistances 100
Ω
on the rear, 1 k
Ω
on the front.
2. Run the commands below.
