16. Resolution Bandwidth Switching Uncertainty
7. If you are testing an analyzer equipped with Option 1DR, press
FREQUENCY, Center Freq, 50 MHz, SPAN 10 kHz and continue with step
8. If the analyzer is not equipped with Option 1DR, stop here.
8. Set the resolution bandwidth and span according to Table 2-29.
9. Press Peak Search (or Search), Marker→, Mkr →CF, Peak Search (or
Search) then record the Marker Delta Amplitude Reading in the
performance verification test record as indicated in Table 2-29.
10.If the analyzer is an ESA-L Series analyzer, repeat step 8 and step 9
for Res BW settings of 300 Hz and 100 Hz with the corresponding
span settings listed in Table 2-29.
11.If the analyzer is an ESA-E Series analyzer, repeat step 8 and step 9
for Res BW settings of 300 Hz through 10 Hz with the corresponding
span settings listed in Table 2-29.
12.If the analyzer is an ESA-E Series analyzer with firmware revision
A.08.00 or later and it is equipped with Option 1D5 (high stability
frequency reference), repeat step 8 and step 9 for all the Res BW
settings listed in Table 2-29.
1 MHz 5 MHz 8)
3 MHz 10 MHz 9)
5 MHz 25 MHz 10)
a. These Res BW Settings must be entered from the keypad;
they cannot be accessed from the step keys or knob.
