Command
FETCh?
Sequence-test Measurement:
If sequence is enabled, results will be sent for each test enabled in the format for single
tests, with a semicolon between the data for each test.
<meas param name>, <test voltage>, <meas param value>, <pass or fail>; <meas param
name>, <test voltage>, <meas param value>, <pass or fail>; <meas param name>, <test
voltage>, <meas param value>, <pass or Lo ramp, Hi ramp, Lo fail, Hi fail, Arc fail, GC
fail, Sys fail>
F?
Returns all the raw data if a measurement is available, in the string
<Status>,<ACTot>,<ACReal>,<ACImag>,<DC>,<IR>,<reserved>,<GndCnt>
For example in AC Hipot mode the string returned could be:
"0,1.3558e-07,1.1165e-08,1.3512e-07, , , ,"
st
where the 1 character of the string is required to determine the status of the tester
0 = No status/testing
1 = Failure
2 = No measurement available (ramping or does not have a valid measurement)
Note: FETCH? must be sent to the unit, when a status "1" is detected, prior to
any additional F? commands being sent. The FETCH? will show the exact
failure mode.
During Hipot measurements it is possible for the F? to return 0.0000mA
prior to a short or other overload condition.
During IR measurements if the reading is outside of the measurement
range F? can return a null field or return –9.9999e+03
*IDN?
Returns instrument identification "QuadTech, Guardian 25X0,xx...xx, software
version".
*ESR?
Returns the read of the event status register.
*STB?
Returns the read of the status byte register.
*ESE?
Returns the read of the event status enable register.
