CALIBRATION

NOTE

For 683X5B models, the frequency ranges for Band 0 and Band 1 are

0.5to 2.2 GHz and 2.2 to 8.4 GHz re- spectively.

NOTE

Before beginning this calibration proce- dure, always let the 682XXB/683XXB warm up for a minimum of one hour.

ALC Slope The following procedure lets you adjust the ALC

DACSlope over individual frequency ranges to compen-

Adjustment sate for decreasing output power-vs-frequency in analog sweep.

The procedure begins by letting you adjust the ALC Slope for band 0 (0.01 to 2.0 GHz), if installed. It then continues letting you adjust the ALC Slope from 2 GHz to the top frequency of the instrument in up to four bands. The band frequency ranges are:

Band 1 2.0 to 8.4 GHz

Band 2 8.4 to 20 GHz

Band 3 20.0 to 40.0 GHz

Band 4 40.0 to 65.0 GHz

During band 1 thru 3/4 ALC Slope adjustment, the 562 Network Analyzer display (Figure 4-8) shows the response from 2 GHz to the top frequency of the model, as adjustment is done band by band.

1.Set up the 562 Network Analyzer as follows:

a.Press the System Menu key.

b.From the System Menu display, select RESET.

c.Press CHANNEL 2 DISPLAY: OFF.

d.Press CHANNEL 1 DISPLAY: ON.

e.Press CHANNEL 1 MENU key.

f.From the Chanel 1 Menu Display, select

TRANSMISSION and SELECT INPUT (NON-RATIO A).

2.Set up the 683XXB as follows:

a.Reset the instrument by pressing SYSTEM then Reset . Upon reset the CW Menu is dis- played.

b.Press Step . The Step Sweep Menu is dis- played.

c.Press FREQUENCY CONTROL , then Full to select the full frequency range of the unit being calibrated.
