Performance Verification Tests

12. Display Scale Fidelity

Setup for linear scale measurement:

1. Set the following parameters on the analyzer:

SPAN, 100, Hz (ESA-E Series only)

SPAN, 300, Hz (ESA-L Series only)

BW/Avg, 10 Hz (ESA-E Series only)

BW/Avg, 100 Hz (ESA-L Series only)

Video BW, 1 Hz

2. Press Peak Search (or Search) on the analyzer.

3. Set the 1 dB and 10 dB step attenuators to 0 dB.

4. Adjust the synthesized signal generator amplitude until the

analyzer marker amplitude reads 223.6 mV ±4 mV.

NOTE Do not adjust the synthesized signal generator amplitude after the

reference is established.

Calculate ideal marker amplitude:

5. Considering Total Actual Attenuation at the 0 dB from REF LVL

setting to be ATref and the Total Actual Attenuation at any other dB

from REF LVL setting to be ATmeas, calculate the Ideal Mkr

Reading, in millivolts, as follows and enter the result in Column 7 of

Table 2-16.

Measure linear fidelity:

6. Perform step 7 to step 9 for each measurement value in Table 2-16.

7. Set the 1 dB and 10 dB step attenuators as indicated in Table 2-16

for the dB from REF LVL settings.

8. Press Peak Search (or Search) on the analyzer and record the marker

delta (∆ Mkr1) amplitude reading as the actual Mkr reading in

Column 8 of Table 2-16.

9. Calculate the Linear Fidelity Error (LFE) as a percentage of

reference level (RL), and record the result in the performance

verification test record as indicated in Column 9 of Table 2-16.
