OPERATIONAL VERIFICATION TESTING
6-24
Differential offset voltage accuracy
6 On the UUT set:
I Bias 0 [V]
<IQ> I Offset 300 [mV]
7 Measure the voltage on the DMM against the limits shown in Table 6-8.
8 On the UUT set:
I Offset −300 [mV]
9 Measure the voltage on the DMM against the limits shown in Table 6-8.
Signal amplitude accuracy
10 On the UUT set:
I Offset 0 [V]
<Catalog>
Select the 20 kHz IQ test tone.
<IQ> IQ Level 4 [V]
11 Measure the voltage on the DMM and convert to pk-pk by multiplying the measurement by
2
2 against the limits shown in Table 6-8.
12 Transfer the cable to the I output and repeat (2) to (11), noting the opposite polarity in (6)
to (9).
13 Transfer the cable to the Q output and repeat (2) to (11) setting the Q Bias and
Q Offset accordingly.
14 Transfer the cable to the Q output and repeat (2) to (11), noting the opposite polarity in (6)
to (9).
