Performance Verification
To verify the performance of the E444xA Option H26, refer to Figure 1-7. In this example,
an 83650B Synthesized Sweeper was used, but a similar RF source could also be used.
CAUTION The Damage Level is reduced to +20 dBm when the Option H26 is
enabled.
1. Set the Signal Source to 5 GHz at –30 dBm. Verify the RF Power using a power meter.
Connect the source to the PSA RF Input.
2. Measure the amplitude on E444xA H26 with preamp off.
3. Turn on the preamp, insuring that the Amp Corr is also on. Refer “Front Panel Key
Select” on page 3-3 and “Flatness Compensation Table” on page 3-5 for more
information.
4. Measure the amplitude on the PSA screen.
The measured amplitude should be ± 5dB of the measured input signal from step 2.
5. Repeat at 15 GHz, 20 GHz, 35 GHz, and 40 GHz.
NOTE Even with option H26 disabled, the instrument may fail the DANL test
when performing the PSA Series Performance Verification Tests. This is
due to the insertion loss in the switches and cables used with H26. If a
failure occurs, refer to “Appendix” on page 4-1 to manually check
DANL. This check can be used to determine if the instrument needs to
be troubleshot for a higher than normal H26 DANL level.
