BIAS C – OUTSIDE LIMIT
 Bias voltage low
 Bias voltage high: The probe bias voltage is beyond specification.
Check the negative 8-volt supply level. If the supply voltage is within
specification, the probe/preamplifier assembly should be replaced. If
the bias voltage is still beyond specification, return for service.
STIM C – OUTSIDE LIMIT
 STIM test low
 STIM test high: A fault exists in the RF signal processing path. Replace
the probe/preamplifier assembly; if the error persists, return for service.
