Power tab
Tx Power Control
Grid
Each column displays various power levels at points spaced evenly across the
radio’s band (as shown in the Frequency Cal Pnt a to e fields, Test Freqs tab).
Each row displays results of the Tx Power Control test at the various
frequency points, at the power levels of Very Low, Low, Medium, and High.
These values will be the DAC settings from the test, from 0 to 1023.
Coupler Cal Power Shows what is calculated for the forward and reverse power of the directional
coupler, as a result of the Tx Power Control test. These values are calculated
using the DAC settings from the Tx Power Control Grid, at very low and
high power, at the bottom and top frequencies of the band.
Power Level Sqrt 0
to 4
Shows constants that are used by the radio during certain power-related
calculations. These values are derived from the square root of each desired
power level, multiplied by 1000.
Test Freqs tab
Rx FE Tune Cal Freq
Pts
Displays frequency points (in Hz) at which the Receiver is calibrated.
Frequency Cal Pnt a
to e
Displays frequency points (in Hz) from which power levels (‘Tx Power
Control Grid’, Power tab) are calculated. Point ‘a’ and point ‘e’ are also used
to calculate the forward and reverse power settings (Coupler Cal Power).
Temperature values Shows high temperature thresholds (in °C) that the radio will use to warn
the user. These values are factory only, and can only be viewed with a hasp
key attached to your PC.
The thresholds are:
■ pending high temperature shutdown,
■ shutdown to very low power,
■ shut off, and
■ the hysteresis value that the radio must return to before the transmitter is
re-enabled.
