53220A/53230A Error Messages A
+313
Channel 3 burst frequency
could not be measured
The carrier frequency could not be measured pos-
sibly due to a frequency shift of the input signal.
See additional errors accompanying this mes-
sage.
+314
Channel 3 pulse ended before
gate closed
The input signal may contain pulses of varying
widths. If using automatic gate control
(SENSe:FREQuency:BURSt:GATE:AUTO ON),
turn automatic control OFF and decrease the gate
time manually using
SENSe:FREQuency:BURSt:GATE:TIME until a
reading is obtained.
+315
Channel 3 power too high
for operation
For continuous wave (CW) measurements signal
power must be < +19 dBm. For pulse measure-
ments signal power must be < +13 dBm.
+316
Channel 3 power too low
for operation
For continuous wave (CW) measurements signal
power must be > -27 dBm. For pulse measure-
ments signal power must be > -13 dBm.
+317
Channel 3 power changed
during measurement
The measurement could not be completed due to
a change (too low or too high) in input signal
power.
+318
Channel 3 input is not a
pulsed signal
The measurement function selected requires/
expects a pulsed signal.
+319
Channel 3 frequency shift
detected during measurement
The FM tolerance of the input signal frequency
ex 50% during the current measurement
gate.
+320
Input signal frequency shift
caused counter overflow
The FM tolerance of the input signal frequency
ex 50% during the current measurement
gate.
+321
Measurement timeout
occurred
The time allotted for an individual measurement to
complete was exceeded. The default time out is
1s. The time out is set from the front panel under
‘Utility’ -> ‘Instr Setup’, or using the
SYSTem:TIMEout command:
+322
Measurement overflow
occurred
A totalizing count (continuous or gated) exceeded
the upper range of 10
15
events.
+514
Not allowed; Instrument
locked by another I/O session
A lock (SYSTem:LOCK:REQuest?) was
requested from another I/O interface.
