Pass/Fail Limit (Specification) Descriptions
26. TXA Output Power at Level 0 (dBm)
26. TXA Output Power at Level 0 (dBm)
Pass/fail limits 26 through 33 set the pass/fail limits for output power
levels 0 through 7 measured at the transmitter’s output terminal. Units
for this pass/fail limit are set by parameter 36. TX Units for Pwr Meas
[0=dBm 1=Watts]. If Watts (1) is selected the software will
automatically covert test limijts to Watts when comparing and
displaying results.
All power level limits are separate pass/fail limits and each can be set
as desired.
Pass/fail limits are determined by using any applicable standard such
as:
• EIA/TIA Standard: Transmitter Output Power
NOTE Values for power levels in the standard are for effective radiated power
(ERP) and not as measured directly from the mobile unit. Power levels
will be higher when measured directly from the mobile unit.
Example
If you are testing Power Class I radios and you desire that the output
power levels should be maintained within the range of +2 dB and
−4 dB
of the nominal values over a specified temperature range, enter the
values in the following table for the Lower Limit and the Upper Limit
for power levels of 0 through 7.
