E4405B, E4407B, and E4408B (Option 1DN)
1. Complete this step only if more than two hours have elapsed since
performing a front-panel calibration of the microwave analyzer.
The microwave analyzer should be allowed to warm up for at least 30
minutes before proceeding.
Complete a front-panel calibration of the microwave analyzer by
performing the following steps:
a. Preset the microwave analyzer.
b. Connect a BNC cable between CAL OUTPUT and 50
Ω Input.
c. Press
CAL, REALIGN LO & IF.
d. Set
FREQUENCY, 300 MHz.
e. Set
SPAN, 20 MHz.
f. Set
AMPLITUDE, –10 dBm.
g. Press
PEAK SEARCH.
h. Press
CAL, REF LVL ADJ and use the ⇑ ⇓ arrows to adjust the DAC
value to a marker amplitude reading of
−10 dBm. Press STORE
REF LVL
.
i. Disconnect the BNC cable from between the CAL OUTPUT and
50
Ω Input.
2. Use the Type-N cable to connect the RF Input to the RF OUT of the
tracking generator as shown in Figure 2-68. Do not connect to the RF
Input of the microwave analyzer yet.
