a. Performance Check
(1) Set TRAN/TEST/RECV switch to TEST (red dot) position and adjust PHASE
control for maximum peak indication of SET POWER meter. Adjust POWER SET control
as necessary to maintain on-scale indication.
NOTE
The PHASE control has several settings at which peak
deflection can be obtained on the power meter. Select the
setting that provides the most stable operation.
technique of (a) through (d) below:
(a) Slowly adjust FREQUENCY control until SET POWER meter indication
dips sharply. Note FREQUENCY MC/10 dial indication.
(b) Slightly increase or decrease toward 8.5 GHz (15.8 GHz) SIGNAL FREQ
control setting and readjust PHASE control to maintain peak indication of power meter.
(c) Continue process of (a) and (b) above until a sharp dip occurs when
FREQUENCY MC/10 dial indicates 850 (1580).
FREQUENCY MC/10 dial to a point at least 100 MHz away from TI signal generator
frequency and adjust POWER SET control for indication of SET POWER on SET
POWER meter.
