Displaying Frequency or Power
You can display frequency or power values above the bars in the trace display. The
displayed frequency is the average instantaneous frequency when the signal is
active.
For CDMA type signals, the frequency option is not recommended; accurate
frequencies for CDMA are not displayed.
Setting the Pass/Fail Limits
The measurement limits setting enables you to alter the value of the upper and lower
test limits. The settings you choose define the location of the limit lines displayed on
the screen. These settings affect the color of the bar graph display and the measured
value: red represents fail, green represents pass, and blue indicates that the limits are
turned off.
• Power Limits: Sets the high and low limits of the channel power. Limits are set
in dB and are relative. Any channel value that is outside of the set limits will
result in a failure indication.
• Frequency Limits: Sets the high and low frequency limits for each channel.
Limits are set in Hz. These settings affect the display color as indicated above,
but there are no limit lines shown on the display.
