ALL FREQUENCY FULL BAND SPECTRUM ANALYZER MODE


The ST5128 has the capability to scan and display the field strength for

all frequencies across the meter’s bandwidth. Pressing the F1 (ALL) soft key
activates the All Frequency Full Band Spectrum Mode. The scan will take
approximately 45 seconds and scan 100 channels.

The meter display for the All Frequency Band Spectrum Mode is shown in Figure
7.
The ST5128 displays the video or audio carrier power levels of TV channels in
the channel list being used (CATV or VHF/UHF). The meter measures channel
power levels between –40 and +60 dBmV. For each channel that has no power,
the meter displays a short (about 10 dB high) vertical line of –40 dBmV.


The All Frequency Band Spectrum Mode can be activated so that the user

can inspect the power of a specified channel in relation to all other channels in a
band by pointing the marker at the bottom of the meter display to any selected
channel video carrier within the frequency spectrum.
