Instrument Messages

10652 EVM Measurement only supports EDGE TCH burst type

10654 Unable to demodulate signal

10655 Input overload

Excessive input power has been detected which will cause the ADC to clip

the signal. Reduce the signal level, change the attenu a t or setting (under

Input menu), or press Restart if the RF Input Range is Auto.

10656 Tx Band Spur measurement does not support this frequency band

The transmit band spur measurement does not support all of the

commercially available frequency bands. You need to change your selection

under Mode Setup, Radio, Band to one of the supported bands.

10657 Pretrigger too long

10658 Valid GSM burst not found for selected timeslot

In a GSM measurement, data was acquired but a GSM burst was not

found, with the timeslot mode enabled.

10701 to 10800: W-CDMA Error Messages (Option BAF) An error number in this

range indicates the instrument has detected an error relating to the W-CDMA personality.

10702 Signal too noisy

10704 Input power too low

The instrument only identifies a channel as active if it meets the default

threshold criteria that it is within 20 dB of the highest power code

channel. The threshold can be chan ged using the Active Set Threshol d

function in the Meas Setup menu.

10768 Cannot correlate to input signal

Cannot correlate to the input signa l and no active channel is found. (fro m

the composite EVM measurement) An active channel must meet the

default threshold criteria that it is within 20dB of the highest power code

channel. The threshold can be changed using the active set threshold

function in the Meas Setup menu.

10772 Burst not found.

Either the signal being analyzed has insufficient power, the rising or

falling edges cannot be detected, or the burst is less than

126 microseconds.

10776 Cannot sync DPCCH pilot.

This error message appears when an in Slot power measurement

(Chip Power) is selected and the DPCCH sync is not done

correctly.
