4-3 Option 21, Transmission Measurement, System Dynamic Range Option Verification
4-4 PN: 10580-00253 Rev. J S3xxE MM
4-3 Option 21, Transmission Measurement, System Dynamic Range
The following test is used to verify the system dynamic range for Site Masters with Option 21, 2-Port
Transmission Measurement, installed.
Equipment Required
• Termination Frequency: DC to 18 GHz Return Loss: 40 dB min. Anritsu Model 28N50-2
• Termination Frequency: DC to 18 GHz Return Loss: 40 dB min. Anritsu Model 28NF50-2
• RF Coaxial Cable Freq: DC to 18 GHz N(m) to N(m), 50 ohm Anritsu Model 15NN50-1.5C
Procedure
1. Verify that the S3xxE is in Transmission Measurement mode and preset the unit.
2. Press the Shift key, then press the Sweep (3) key.
3. Verify that High Dynamic Range is set to On
4. Verify that the Output Power is set to High.
5. Press the Measure soft key.
6. Press the Start Cal soft key and follow the on screen instructions to perform calibration.
7. After the calibration is complete, disconnect one end of the cable and connect loads so both the RF Out
(Reflection In) and RF In ports are terminated.
8. Press the Sweep soft key and then press Averaging. Confirm that Averaging Off is pressed, indicated by
the red dot in the top right hand corner.
9. Press the Amplitude soft key and set the Top to –50 dB and Scale to 10 dB/div.
10. Press Shift, Limit (6), and set the Limit to On.
11. Press the Multi-Segment Edit soft key and verify that the Point Frequency is set to 2MHz.
12. Press Amplitude vertical soft key and set the limit to –80 dB.
13. Press Add Point, press Point Frequency, and enter 4.0 GHz.
14. Press Amplitude vertical soft key and enter –80 dB.
Perform
Step 15 through Step 18 for S36xE units only,
15. Press Add Point, press Point Frequency, and enter 4.01 GHz.
16. Press Amplitude vertical soft key and enter –70 dB.
17. Press Add Point and press Point Frequency, and enter 6.00 GHz.
18. Press Amplitude vertical soft key and enter –70 dB.
19. Verify the display of the system dynamic range is below the limit lines (the data will be unstable, but
should remain below the limit lines.)
20. Use a marker to find the maximum peak of each frequency band and enter the value in dB in Table A-17,
“Option 21, VNA System Dynamic Range Verification”.
