Error Messages
This error occurs when the internal local signal of the instrument cannot be unlocked.
There is the possibillity of a device failure. Contact a Keysight Technologies sales office or
the company from which you bought the device.
D
-222 Data out of range
A data element (not violating the standard) outside the range defined by this instrument has
been received. This error occurs, for example, when an integer-based command for which
the parameter can be rounded exceeds the range of -65536 to +65536 or when a
real-number-based command for which the parameter can be rounded exceeds the range of
-9.9e37 to +9.9e37.
280 DC control overload
The current through the DC CONTROL connector is too large.
270 DC power overload
The current through the DC POWER connector is too large.
373 Downconverter Fan Stop
This error occurs when the fan of the downconverter stops. Contact Keysight
Technologies’ Customer Contact given at the end of this guide or the company from which
you bought the device.
354 Downconverter IF not found
This error occurs when the down-converted signal does not fall into the expected IF range.
The deviation between the set nominal frequency and the actual input signal's frequency
may be too large. Execute the carrier search function, and set a correct nominal frequency.
352 Downconverter Oven Cold
This error may occur due to the unlocked PLL because the oven is not heated sufficiently
for some time after the downconverter is turned on. Heat the oven for some time with the
power on.
374 Downconverter P5V power fail
This error occurs when the 5-V power of the downconverter fails. A device failure is
suspected. Contact Keysight Technologies’ Customer Contact given at the end of this
guide or the company from which you bought the device.
353 Downconverter Ref Input Level Low
This error occurs when the level of the 10-MHz reference signal to the downconverter is
low.
372 Downconverter Ref PLL unlocked
This error occurs when the PLL circuit of the downconverter is unlocked during
measurement. This error may occur when the carrier frequency of the measurement sample
is unstable.
It may occur also due to the same reason as "Downconverter Oven Cold."
375 Downconverter test failed
This error occurs when the self-test of the downconverter fails. A device failure is
suspected. Contact Keysight Technologies’ Customer Contact given at the end of this
