Cause
Operation not
possible with external
clock
Too much data
received.
Hardware error. An
amplifier has an
overload condition.
Harmonic contents of
user defined wave
shape is too high and
could damage
amplifier output
stage.
An amplifier failure.
Can be reported at
any time.
One or more auxiliary
units is not powered
up or not working.
Over voltage
detected on output
Peak current limit
exceeded.
Frequency error
during self-test.
Self test error phase
angle
Too much DC content
in loaded ARB
waveform.

Remedy
Switch to internal sync. (Default)
Break up data in smaller blocks.
Check amplifier balance adjustment.
If error persists contact CI service at
support@programmablepower.com
Reduce harmonic content or reduce
fundamental frequency programmed.
Determine which amplifier is at fault
with self-test or checking LED on
Relay Board. Replace amplifier.
Turn on all auxiliary units.
Check output voltage for correct RMS
value.
Peak current exceeded. Could be
caused by switching EUT on or off.
Correct frequency was not measured
during self-test. May be result of 801
error.
Correct phase angle was not
measured during self-test. May be
result of 801 error.
Check waveform programming.
