WLAN TX Measurements Option Messages (K91/K91n)
The list of possible warning & error messages is shown below.
This option is available from firmware version 1.20.
Status bar message Description
Gate length too small – must be greater than 1 This message is only displayed for the FFT measurement. This
message indicates that there are no samples contained within the
gating lines. Increase the Gate length and then, in the sweep menu,
press the Refresh softkey to remove this error.
No valid analyzed bursts within gating lines This message is only displayed for the PVT measurement. This
message indicates that there are no complete & valid bursts contained
within the gating lines. Increase the Gate length and then, in the sweep
menu, press the Refresh softkey to remove this error.
No bursts found This message is displayed if no valid burst was detected in the input
data. To correct this problem check the following:
The connections between the DUT and analyzer are correct.
The input signal is of a sufficient level.
The capture time is long enough to capture at least one complete burst.
If running with a Free Run trigger then the capture time must be greater
than the burst length (ideally at least twice the burst length) to ensure
that a complete burst is recorded.
Check that the demod settings are correct.
No bursts of desired type to analyze This message is displayed if bursts are found, but none of desired type
to analyse. Check that the setting for Burst Type is correct.
No signal found This message is displayed when an automatic level detection
measurement is executed and the measured signal level is lower the
permitted minimum value.
No power trigger for Spectrum Mask ETSI This message is displayed when the Spectrum Mask ETSI
measurement is selected whilst the trigger is set to power. No action is
required as the trigger is automatically set to Free Run in this case.
Signal overload detected This message is displayed when the OVLD enhancement label is
displayed and indicates that the input mixer is overloaded. If this
message is displayed then try increasing the setting for the Signal
Level parameter (or settings Auto Level). If this does not clear the
problem then an external attenuation may need to be applied.
