Atec Tektronix-1502 - Manual (Page 39)

TM 9-4935-601-14-3&P
CALIBRATION PROCEDURE
The first part of this procedure checks the electrical characteristics of the 1502 that appear in the
Specification section of this manual. This procedure can also be used by an incoming inspection facility to
determine acceptability of performance. The second part of this section contains a detailed adjustment
procedure.
It is recommended that these elementary checks be performed before those in the DETAILED CHECKS
AND ADJUSTMENTS section; these checks will identify most conditions calling for troubleshooting and repair.
To aid in troubleshooting, the probable problem area(s) are given after each applicable step. Refer to the Block
Diagram and Schematics in Section 8 as an aid in locating components, test points and circuits.
