Fluke 6080A - MID-LEVEL ACCURACY TEST 4-7.

PERFORMANCE TESTS
8. Repeat steps 4 through 7 with the UUT programmed to each of the following
frequencies:
14, 20, 40, 80, 160, 320, 550, 640, 700, 850, 950, 1024 MHz
Table 4-3 is an example of this procedure in which the measured power and the error
calculations are shown. This example is for one frequency, and these measurements
and calculations are repeated at other frequencies. In this case, the section errors and
the sum of the section errors are within the test limits; therefore, the unit passed the
high-level accuracy test.

MID-LEVEL ACCURACY TEST 4-7.
The level accuracy is verified using a power meter with a low-level power sensor. This
verification is done from -24 to -66 dBm at frequencies of 10, 14, 20, 40, 80, 160, 320,
550, 640, 700, 850, 950, and 1024 MHz.
REQUIREMENT:
Amplitude accuracy is:
< ±1.5 dB from 0.5 to 1024 MHz
TEST EQUIPMENT:
• Power meter
• Power sensor (Low-Level)
REMARKS:
This test, in conjunction with the high-level accuracy test and the low-level accuracy
test, verifies the overall level performance of the UUT.
