4286A Measurement Time
Total measurement time of the LCR meter is calculated as follows:
/EXT TRIG
#
A
Contact check
Analog measurement
/INDEX(until the end of list sweep)
Comparator
#
B
Measured value display
Handler signal output
/EOM
Data transfer through GPIB
By incrementing the averaging factor by 1, total measurement time becomes 5ms
1
longer. For example, analog measurement time is 30ms ( = 15ms + 5ms
select 4 for the averaging factor.
You can turn the measured value display ON/OFF on the front panel. When you set this
function to OFF, the duration of time between EOM(End of Measurement) and next trigger
becomes shorter.
The data transfer time through GPIB shown above includes the time required to input a
contact check comparator signal and 2-point measurement results at the same time using the
HP 9000 Series 360.
Example
The following shows the approximate duration of time required to make a 2-point measurement
by list sweep. We assume that the measured value display, comparator, and handler signal
output are respectively OFF, ON, and ON.
Calculating the time for each operation from the above, we obtain the following:
Contact check 15ms
