Equipment Required; Check Procedure - Tektronix 2A61 Instruction Manual

Type 2A61
SECTION 5
PERFORMANCE CHECK
Introduction
This section of the manual provides a means of rapidly
checking the performance of the Type 2A61. It is intended to
check the calibration of the instrument without the need for
performing the complete Calibration Procedure. The Perform-
ance Check does not provide for the adjustment of any inter-
nal controls. Failure to meet the requirements given in this
procedure indicates the need for internal checks or adjust-
ments, and the user should refer to the Calibration Procedure
in this manual.
EQUIPMENT REQUIRED
The following (or equivalent) equipment is required for a
complete performance check of the Type 2A61. Equipment
specifications given here are the minimum requirements for
making the performance check. All test instruments are
assumed to be calibrated and operating within their rated
specifications. If substitute equipment is used, it must meet or
exceed the specifications of the recommended equipment.

ber 012-0072-00.
PERFORMANCE CHECK PROCEDURE
The following procedure uses the equipment listed under
Equipment Required. If substitute equipment is used, con-
nections and control settings may need to be altered to cor-
respond to the characteristics of the equipment used.
Preliminary Procedure
1. Install a Type 2B67 in the right hand plug-in compart-
ment in the Type 561A Oscilloscope.
2. Install the Type 2A61 plug-in to be checked in the left
hand plug-in compartment in the Type 561A Oscilloscope.
3. Turn the Type 561A Oscilloscope Power switch to On
and allow a warm-up period of 20 minutes at 25° C, 5°
C (77° F, +9° Fh.
