Anritsu 37 D Series, Maintenance Manual, Page: 67 / 190

Required Equipment
q Windows-based PC with Windows 95 or higher.
q National Instruments GPIB interface card and associated soft-
ware driver compatible with the installed Windows operating
system.
q Standard GPIB interface cable, such as Anritsu part number
2100-2, must be connected between the VNA and the PC.
q Anritsu 365X calibration kit that matches the test port connec-
tors of the VNA must be used. A sliding termination is required
only if the Source Match or Directivity tests are to be performed.
Only the female components of the calibration kit will be used.
q High quality RF cable suitable for the frequency range of the in-
strument. Anritsu 3670 or 3671 series throughlines are strongly
recommended.
q High quality female to female adapter, such as Anritsu part num-
ber 33KFKF50B. Necessary if the above cable does not have a fe-
male connector on both ends.
NOTE
SMA adapters (with a white teflon dielectric) are too poor in
quality even for the lowest frequency VNAs.
Additional Required
Equipment
q The Frequency Accuracy test requires an EIP brand frequency
counter. Most models are acceptable, but GPIB, Band 3, and Ex-
ternal 10 MHz reference input capabilities are required.
q The Port 1 Power test requires an Anritsu model ML24XX power
meter with an appropriate power sensor. Other meters and sen-
sors, as shown in Table 1-1, are also useable.
q The Source Match test requires an Anritsu Assurance Airline,
such as model T2023-2 or T2025-2, typically available only from
Anritsu Service Centers.
q The Directivity test requires an Anritsu Assurance Airline and
offset termination, such as model 29KF50-15 or SC4417, typically
available only from Anritsu Service Centers.
Installation and
Launching the Test
Program
The program is a stand alone executable requiring that the National
Instruments GPIB software parameters all be set to default condi-
tions. The user will be asked to create the folder “C:\37000” for data
storage, if that folder does not already exist on the PC. Additionally,
the GPIB settings that are required for the 2300-496 Verification Soft-
ware will also work with the 3700TEST.EXE program.
