• Function keys
Main function keys:
[Channel] F1: Changes the channel number.
[Reference Level] F3: Changes the reference level.
[OccBW Ratio] F4: Sets the percentage of total power that resides in the occupied bandwidth.
Initial Value: 99.0 %
Range: 80.0 to 99.9 %
Resolution: 0.1
[RBW] F5: Displays the resolution bandwidth (RBW) menu.
Range: 10 kHz, 30 kHz (Initial value)
Function keys:
[Measure Method] F7: Displays the measurement method (99 % method) selection menu.
[Spectrum] F7: Measures the occupied frequency bandwidth by using the spectrum analyzer
method.
VBW: 30 kHz
SWP Time: When Data Rate is Full : 100 ms
When Data Rate is 1/2 or less : 10 s
