Level Data
Level Uncertainty
Test method
The level uncertainty is measured in two steps. First, the frequency
response is measured at a fixed level with high frequency resolution.
Then the level dependant uncertainty is measured at fixed frequencies
over the specified range.
Test equipment - Power meter (Table 1-1, item 8)
- Spectrum analyzer (Table 1-1, item 18)
- Low-noise preamplifier (Table 1-1, item 9)
Test method for levels in measurement range of power meter
Test setup
Connect power meter to RF output socket.
Measurement
Setting on DUT:
- Levels : +18 dBm in level Mode AUTO
Measure the level P
absolute
at the recommended test frequencies up
to RF
max
.
The level error is the deviation of the measured level from the set
value.
Repeat this measurement at + 13 dBm in level Mode OFF (Sample
& Hold) at 200 kHz, 25 MHz, 100 MHz, 1.1 GHz, 2.2 GHz, 3.2 GHz
and 6 GHz
Recommended test
frequencies for the level
