1-5 OPERATION Each verification kit consists of three standards, each are supplied
with S-parameter data. Each standard verifies a primary S-parameter,
as follows:
q20 dB Attenuator — S21,S
12 Magnitude and Phase
q50 dB Attenuator — S21,S
12 Magnitude and Phase
qMismatch Attenuator — S11,S
22 Magnitude
Uncertainty windows are provided at each data point. The uncertainty
associated with the primary S-parameter for each device is small. Con-
versely, the uncertainty window can be large for some of the other
S-parameter data.

Performance Verification
2-1 GENERAL Verifying the performance of the Verification Kit components is auto-
mated. The procedure is provided on floppy disk. The program is titled
ANRITSU 2300-354 Vector Network Measurerment System Perfor-
mance Verification, and is provided with a User’s Guide, Anritsu Part
Number 10410-00216. This User’s Guide and its program diskette are
included at the end of this manual. In performing the verification pro-
cedure, you will be asked to extend the test ports using test cables.
This is shown in Figure 2-1.

2-2 VERIFICATION PROCESS Verification is a straightforward process intended to show that a vec-
tor network measurement system (VNMS) is performing to specifica-
tion. It can usually be accomplished in less than an hour, after waiting
out the typical one-hour warm-up period. It is important to recognize
that the process involves four hardware components:
qVNMS
qCalibration kit
qCable(s)
qVerification kit
To have a successful verification process, all of the above items must
be in good condition and properly connected.
While the primary purpose of the verification process is to validate
performance of the VNMS; failure is more often caused by factors
other than the VNMS (see next paragraph). Consequently, it is incum-
bent on the operator to examine these other factors before pronounc-
ing the VNMS as “out of specification.”
2-3 FACTORS AFFECTING
VERIFICATION
PERFORMANCE
The following paragraph discuss factors that can cause verification
failure in a VNMS.
Cables A good method for evaluating cable performance is to calibrate a
VNMSa simple frequence response calibration will do, or in an
uncalibration system you can use trace memory to store the response
and then select Data/Memory to view it. In either case, you should see
a straight line on the display. Select a 1 dB/Div scale and observe the
display as you move the cables slightly up and down or left and right.
Small variations are acceptable and they should be minimized when
the cable is returned to its orginal position. Any erratic changes, such
as spikes in the display, would indicate a defective cable. The cable
should be replaced before the verification process is begun.
Sliding Loads Most calibrations require a sliding load. Sliding loads must be handled
carefully. When the slide in in the forward position, the center conduc-
tor should be centered (or reasonably so). When centered, it is easy to
connect the sliding load to the test port. If, however, the slide is posi-
tioned toward the back end of the sliding load, the center conductor is
not well supported and it will be off center. Attempting to connect the
test port in this circumstance will like result in center conductor dam-
age. Consequently, ENSURE THAT THE SLIDE IS IN THE FOR-
WARD POSITION BEFORE ATTEMPTING TO CONNECT THE
SLIDING LOAD.

Preview the Display When running the verification software, there is a step that requires
the VNMS to be calibrated. This step places the VNMS in LOCAL
(Manual) control and the program waits for the operator to press the
Enter key. Pressing Enter tells the program that the calibration is com-
plete and returns the VNMS to REMOTE control.
Prior to pressing the Enter key, connect the 20 dB attenuator included
in the verification kit. When this attenuator is connected, the observed
response should be smooth and free of “glitches” (Figure 2-1). It should
be possible to firmly tap the test device’s input and output connections
without seeing any significant distortion. Figure 2-2 is typical of the
display if a connection is not properly tightened or is defective.

Maintenance Instructions
3-1 INTRODUCTION This chapter provides instructions and discussion on the care and use
of precision connectors.
3-2 PRECAUTIONS FOR
USING CONNECTORS The following are precautionary notes related to the use of connectors. For specific information on setting pin depths on sliding terminations,
refer to the MS462X Operation Manual, Chapter7.
Pin Depth Before mating, measure the pin depth (Figure 3-1) of the device that
will mate with the RF component, using a ANRITSU Pin Depth Gauge
or equivalent (Figure 3-2). Based on RF components returned for re-
pair, destructive pin depth of mating connectors is the major cause of
failure in the field. When an RF component is mated with a connector
having a destructive pin depth, damage will likely occur to the RF
component connector. (A destructive pin depth has a center pin that is
too long in respect to the connector’s reference plane.)

Figure 3-2. Pin Depth Gauge

Pin Depth Tolerance The center pin of RF component connectors has a precision tolerance
measured in mils (1/1000 inch). Connectors on test devices that mate
with RF components may not be precision types and may not have the
proper depth. They must be measured before mating to ensure suit-
ability. When gauging pin depth, if the test device connector measures
out of tolerance (Table 3-1) in the “+” region of the gauge (Figure 3-2),
the center pin is too long. Mating under this condition will likely dam-
age the termination connector. On the other hand, if the test device
connector measures out of tolerance in the “–” region, the center pin is
too short. While this will not cause any damage, it will result in a poor
connection and a consequent degradation in performance.

Over Torquing
Connectors Over torquing connectors is destructive; it may damage the connector
center pin. Finger-tight is usually sufficient, especially on Type N con-
nectors. Never use pliers to tighten connectors.
Teflon Tuning
Washers The center conductor on most RF components contains a small teflon
tuning washer located near the point of mating (interface). This
washer compensates for minor impedance discontinuities at the inter-
face. The washer’s location is critical to the RF component’s perform-
ance. Do not disturb it.
Mechanical Shock RF components are designed to withstand years of normal bench han-
dling. However, do not drop or otherwise treat them roughly. They are
laboratory-quality devices, and like other such devices, they require
careful handling.
3-3 CLEANING
INSTRUCTIONS Connector interfaces, especially the outer conductors on the GPC 7 and SMA connectors, should be kept clean and free of dirt and other
debris. Denatured alcohol is the recommended applicator. Figure
3-3 illustrates cleaning male and female connectors.

VERIFICATION CLEANING
KITS INSTRUCTIONS

NOTE
Most cotton swabs are too large to fit in the smaller con-
nector types. It is necessary to peal off most of the cotton
and then twist the remaining cotton tight. Be sure that the
remaining cotton does not get stuck in the connector.
The following are some important tips on cleaning connectors:
qUse only denatured alcohol as a solvent.
qAlways use an appropriate size of cotton swab.
qGently move the cotton swab around the center conductor.
qNever put lateral pressure on the connector’s center pin.
qVerify that no cotton or other foreign material remains in the con-
nector after cleaning.
qOnly dampen the cotton swab. Do NOT saturate it.
qCompressed air can be used to remove foreign particles and to dry
the connector.
qVerify that the center pin has not been bent or damaged.
Figure 3-4 illustrates how to clean connectors.
