Error Message

Description

 

 

 

 

 

 

 

 

 

 

 

Displayed (on the frequency mode title bar) when (1) the

 

ERROR

 

 

 

 

 

output frequency is not phase-locked, (2) an invalid

 

 

 

 

 

frequency parameter entry causes a frequency range

 

 

 

 

 

error, or (3) an invalid pulse parameter entry causes a

 

 

 

 

 

pulse modulation error.

 

 

 

 

 

 

 

 

 

 

Displayed (in the frequency parameters area) when the

 

LOCK ERROR

 

 

 

 

 

output frequency is not phase-locked. The frequency

 

 

 

 

 

accuracy and stability of the RF output is greatly reduced.

 

 

 

 

 

Normally caused by an internal component failure. Run

 

 

 

 

 

self-test to verify malfunction.

 

 

 

 

 

 

 

 

 

 

 

Displayed (in the frequency parameters area) when (1)

 

RANGE

 

 

 

 

 

the analog sweep start frequency entered is greater than

 

 

 

 

 

the stop frequency (683XXB models only), (2) the dF

 

 

 

 

 

value entered results in a sweep outside the range of the

 

 

 

 

 

instrument, (3) the step size value entered is greater than

 

 

 

 

 

the sweep range, or (4) the number of steps entered

 

 

 

 

 

results in a step size of less than 1 kHz (0.1 Hz with

 

 

 

 

 

Option 11) or 0.1 dB. Entering valid values usually clears

 

 

 

 

 

the error.

 

 

 

 

 

 

 

 

 

Displayed (in the frequency parameters area of the

 

SLAVE

 

 

 

 

 

Master 68XXXB) during master-slave operation in VNA

 

 

 

 

 

mode when the slave frequency offset value entered

 

 

 

 

 

results in a CW frequency or frequency sweep outside the

 

 

 

 

 

range of the slave 68XXXB. Entering a valid offset value

 

 

 

 

 

clears the error.

 

 

 

 

 

 

 

Displayed (in the modulation status area) when one or

 

ERR

 

 

 

 

 

more of the following error conditions occurrs:

 

 

 

 

 

(1) The external AM modulating signal exceeds the input

 

 

 

 

 

voltage range. In addition, the message “Reduce AM

 

 

 

 

 

Input Level” appears at the bottom of the AM status

 

 

 

 

 

display. (Continued on next page)
