Center Freq. Setting: Set up the Center Freq. per each Channel.
Center Freq. Range: 851.000000 ~ 869.000000 (MHz) Ref: DL Freq.
Digital Gain Setting: DL/UL gain control per each channel *
Digital Gain Control Range: +/- 5 dB in steps of 0.5 dB
Start Freq.: Calcuate Center Freq. - (Bandwidth/2) (Display Only)
Stop Freq.: Calcuate Center Freq. + (Bandwidth/2) (Display Only)
* An additional gain offset between -5 and +5 dB can be set for each defined channel to compensate
components with frequency-dependent insertion loss, e.g. external filters or splitters. The end-to-end
gain (total system gain) including external components (not antennas) must not exceed a gain of 90 dB
.
If you require more detailed information with an example of an end-to-end gain equation, ask our
Technical Support (for contact data, please refer to chapter
1.6.1 ).
Once you have finished Channel settings, press the Save button to change the settings.
5.6.12. Digital Channels (Class B mode)
Special circumstances, such as high carrier density combined with low group delay or a
combined use of FirstNets Band 14 with narrow PS carriers, require a mix of the flexible
filters of a class A repeater and the low group delay of a class B repeater. To cover
these requirements as well, the digital class A repeater has been designed and granted
by FCC to be easily configured as a class A or class B repeater.
COMPLIANCE Notice:
When using Class B mode, you MUST register the PSR as a Class B signal booster (as
defined in 47 CFR 90.219) online at
www.fcc.gov/signal-boosters/registration .
To use the Class B mode, simply choose a filter above 75 kHz (marked in red), observe
the WARNING message, and accept it by pressing
Ok .
