An alternative method to see the average of 5000 readings is to use
the Math function to set a Block Average of 5000 readings. With
Block averaging set, the display shows one reading for every trigger,
the value being the average of 5000 individual 200
measurements, representing the topline of the applied square wave.
As usual,  can be used to make this a continuous
measurement. If continuous were the desired behavior originally, the
Trigger/Arms Count is irrelevant in this particular example and could
have been left at 1. The MATH is performing the count.
Example 8
Measurement: Starting at midnight on 5th October 2018 you want the Product to
take a group of 50 readings spaced at 30 second intervals starting on the hour
for 3 days. The Product is in the default trigger mode (free-run) and remote
commands are used instead of the front panel.
Solution: Use the Epoch mode to set the start and stop times. When Epoch is
the selected Initiate mode, Initiate is Continuous OFF outside the Epoch times,
Continuous ON between them.
The Trigger layer Timer is set to 30 seconds to determine the spacing of the
individual readings. Starting from the default state the bus commands are:
TRIGger:SOURce TIMer
TRIGger:TIMer 30
TRIGger:DELay 0
The Trigger layer Count is set so 50 readings are taken before exit upwards from
the Trigger layer into the Arm1 layer.
TRIGger:COUNt 50
Arm1 layer Timer is set to 3600 seconds (1 hour)
ARM1:TIMer 3600
The Epoch start is set to the start time of midnight on 5th October 2018. The end
time is set just after the last hourly sequence starts.
INIT:EPOCh 2018:10:05:00:00:00, 2018:10:07:23:01:00
