1-2 INTRODUCTION
This chapter provides illustrations and contents for
models 36585K and 36585V Calibration Kits.
1-3 PURPOSE
The calibration kits contain all of the precision
components and tools required to calibrate an
Anritsu Vector Network Analyzer System for a
12-term error-corrected measurement.
AutoCal has been characterized by Anritsu and the
characterization file is included for use by the host
VNA. It is valid for 1 year from time of shipment.
The characterization cycle for the 36585-Series
AutoCal is 12 months assuming proper use and
care of the module and its connectors.
AutoCal can be characterized using the MS4640x
Series VNA, following the instructions in the VNA
Operation Manual, however Anritsu can only
guarantee meeting its published specifications with
Anritsu characterized AutoCals.

Chapter 2 — Maintenance Instructions
2-1 INTRODUCTION
This chapter provides instructions and discussion on
the care and use of precision connectors.
2-2 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
Vector Network Analyzer Operation Manual.
Pin Depth
Before mating, measure the pin depth (Figure 2-1) of
the device that will mate with the RF component,
using an ANRITSU Pin Depth Gauge or equivalent
(Figure 2-2). Based on RF components returned for
repair, 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.)
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 suitability. When gauging
pin depth, if the test device connector measures out
of tolerance (Table 2-1) in the “+” region of the gauge
(Figure 2-1), the center pin is too long. Mating under
this condition will likely damage 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 connectors.
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 interface. The washer’s location is critical to the
RF component’s performance. Do not disturb it.
Mechanical Shock
RF components are designed to withstand years of
normal bench handling. However, do not drop or
otherwise treat them roughly. They are laboratory-
quality devices, and like other such devices, they
require careful handling.
2-3 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 on the following page illustrates
information about cleaning male and female
connectors.
The following are some important tips on cleaning
connectors:
•Use only denatured alcohol as a solvent.
•Always use an appropriate size of cotton swab.
•Gently move the cotton swab around the center
conductor.
•Never put lateral pressure on the connector’s
center pin.
•Verify that no cotton or other foreign material
remains in the connector after cleaning.
•Only dampen the cotton swab. Do NOT
saturate it.
•Compressed air can be used to remove foreign
particles and to dry the connector.
•Verify that the center pin has not been bent or
damaged.
Note
Most cotton swabs are too large to fit into the
ends of the smaller connector types. In these
cases it is necessary to peel 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.

Figure 2-3. Cleaning Connectors
Do NOT use Industrial Solvents or Water on connector. Use only Denatured Alcohol.
Dampen only, DO NOT saturate.
Use only denatured alcohol and the proper size of cotton swab. Gently rotate the swab
around the center pin being careful not to stress or bend the pin or you will damage
the connector.
Do NOT put cotton swabs in at an angle, or you will damage the connectors.
Do NOT use too large of cotton swab, or you will damage the connectors.
