5-2 RECOMMENDED
TEST EQUIPMENT
The following test equipment is required to perform the procedures in
this chapter:
q
Anritsu ML2430A Series Power Meter
q
Anritsu MA2472A Power Sensor
q
Anritsu MF2412B Frequency Counter or Equivalent
q
Anritsu 3670 Series Throughline
5-3 TEST CONDITIONS The equipment must be operated under controlled conditions of tempera
-
ture and humidity in order to meet its specified precision and stability.
Refer to Section 4-2 for temperature and humidity requirements.
5-4 PRE-TEST SETUP 1. Prior to making any precision measurements, allow the equipment
to warm up for at least one hour from power on. If the power supply
is interrupted for any reason, allow a similar settling period.
2. Verify that the power meter GPIB address is 13 (default). Refer to
the ML2430A Series Power Meter Operation Manual (10585-00001).
5-5 10 MHz
CALIBRATION
PROCEDURE
This procedure guides the operator through the automatic calibration
routine (when an EIP frequency counter is used) or the manual calibra-
tion routine (when an Anritsu frequency counter is used) for the
MS462XX Vector Network Measurement System. The 10 MHz calibration
is used to tune the internal 10 MHz reference oscillator to be within the
required tolerance.
This procedure uses the MS462XX internal diagnostics and calibration
menus in conjunction with a suitable frequency counter and an external
10 MHz reference source.
NOTE
The internal 10 MHz reference of the frequency counter can
be used if it has a high stability oscillator option installed.
