Performance Verification Tests
11. Sweep Time Accuracy
accuracy as follows:
NOTE The sweep time accuracy is defined as a percentage of the indicated
sweep time, not of the indicated signal separation. Therefore, it is
appropriate to divide the difference between the marker delta (
Mkr1)
reading and the nominal signal separation by the sweep time, rather
than dividing by the nominal signal separation.
12.Record the calculated sweeptime accuracy in Table 2-12.
13.If the analyzer is not equipped with Option AYX, fast time domain
sweeps, or Option B7D, DSP and Fast ADC, repeat step 9 through
step 12 only for sweeptime settings between 5 ms and 10 s as
indicated in Table 2-12. For each sweeptime setting, set the function
generator to the frequency indicated in Table 2-12.
14.If the analyzer is equipped with Option AYX, fast time domain
sweeps, or Option B7D, DSP and Fast ADC, repeat step 9 through
step 12 for all sweeptime settings as indicated in Table 2-12. For
each sweeptime setting, set the function generator to the frequency
indicated in Table 2-12.
