MRK960 dual true diversity receiver
Walk test
The WALK TEST function records the RF level of the two antenna inputs, separately, for a total time of 90 sec-
onds. Using the first button, it is possible to choose what to plot: the rf level of the antenna A or B, the Max
value between antenna A and B or both antenna levels separately. Press START and walk on your area with a
wirelss MIC (transmitting at the current frequency) while receiver records all received RF levels. At the end of
the sweep time it is possible to have a look on the graph and check if there are some "hole of RF signals" and
evaluate your wireless coverage.
Finally push the 3rd button (EXIT) to leave this fucntion. As "rule of the thumb", the signal coverage of the
stage could be considered good if, in all the stage, the signal "MAX AB" is never lower than 10µV or 20dBµV.
The plot in the picture, shows a very low coverage with some areas not covered by the two receiving antennas.
In this case probably the position of the antennas must be changed and/or the gain of the boosters adjusted.
Note: the unit for RF level is the same chosen for the squelch level (dBuVolt or uVolt)
OPTIONS:
Name
The options NAME allow you to change the name of the receiver. This is the name displayed in the top of the
display in the main view and is the name sent to the transmitter with the sync function (for transmitters with
this advanced capability).
Display Brightness and Timeout
Display brightness allows to change the brightness of the display from 1 to 15 level (step 1 dB).
Display LOW Timeout [0÷120 sec] controls display behaviour as follow:
- After a first timer timeout without any input on the receiver (buttons or wheel) the display gost on "RE-
DUCED BRIGHTNESS MODE"
- After another timer timeout, the receiver goes into "LOW BRIGHTNESS MODE", and leaves current menu to
be back on TOP MENU.
Display OFF Timeout: [OFF, 5÷240 min] after the timeout without any input on the receiver (buttons or wheel)
the display switches off. (OFF=display always power on.)
NOTE: Each receiver has indipendent display parameters.
Boost active on antenna
allows to select which antenna input (A, B or A+B) has to be powered on by pressing BOOSTER button
from the front panel.
Use the knob to change the name and the buttons to save
or exit from the function (12 alphanumeric characters: A-Za-
z0-9, case-sensitive).
