Performance Test & Calibration
4.1 General
Information is this section is useful for periodic evaluation of the 8003 Precision Scalar Analyzer and its
power sensors. These tests can also be used for incoming inspection testing when the instrument is first
received, if required.
If the 8003 has not previously been used, this manual should be reviewed to ensure that the instructions
covering power requirements (Chapter 1) and GPIB address selection (Chapter 2), for example, have
been complied with before the instrument is turned on. Prior to starting the following procedures, the
instrument should be allowed to warm up for at least 30 minutes to assure maximum stability during
testing.
The Specification Test for the Calibrator Output Power Reference Level given in this section is valid
for an ambient temperature range b15
°
C and +35
°
C (+59
°
F to +95
°
F).
The instrument plus power sensor linearity test is valid when the sensor has been calibrated using the
front panel calibrator at a temperature between 0
°
C and +50
°
C (+32
°
F to +122
°
F), and if operating
within ±5
°
C (±9
°
F) of that calibration temperature.
It is recommended that the verification be done in the order described since some of the steps use the
configuration from a previous step.
As an aid to executing the steps presented, keystroke sequences used on the 8003 are shown in the outer
column of the page. Also, as in the preceding chapters, a distinction is made between the front panel
“hardkeys” and the CRT adjacent “softkeys”. The “hardkeys” are shown in
BOLD
, for example,
[CONFIG]
, and the softkeys are shown in ITALICS, for example, [SENSORSAC/DC].
For information on how to calibrate the 8003 refer to Chapter M2, Maintenance, in the 8003
Maintenance Manual (P/N 20791-001).
