CAUTION
The cable center conductor is fragile and will be seriously damaged if the
cable is stretched, bent too tightly, or bent too oft en. Cables break when the
bend radius is too small—less than 2.5” (6 cm) for 1.85 mm cables, and less
than 4” (10 cm) for 2.4 mm cables.
Use the following guidelines with cables:
• Never coil the cable too tightly.
• Never allow the cable to hang down from an instrument test port, or a
storage fixture, or while holding it.
• Never bend the cable an excessive number of times.

General Information
The Cable Sets
The Cable Sets
The Agilent 85133E/F/H flexible cable sets are designed for use with Agilent network
analyzers that have male NMD-2.4 mm test ports.
85133E
The 85133E set contains a single cable. Use it when a DUT is connected, with the
appropriate adapter, directly to the test set test port. See Figure 1-1.
85133F
The 85133F set contains two cables. Each is shorter than the 85133E cabl e. Use the
85133F cables when a DUT is connected between cable ends. See Figure 1-1.
Figure 1-1 Cable Configurations
85133H
The 85133H set contains a single cable – the -f- to -m- cable from the 85133F cable set. It is
shorter than the 85133E single cable. See Figure 1-1.
Connector Designators
NMD Connectors
NMD denotes a connector that has larger than standard coupling threads for greater
stability. NMD connectors are used on test cables, test ports, test port adapters, and test
port cables.
Female slotted NMD test port connectors are used on the test set end of adapters and
cables, and cannot be connected to standard male connectors.
Male NMD connectors are used on tes t sets (as test p orts), and on the DUT end of adapters
and cables. Male connectors have both the larger threads (for use with test port adapters)
and standard threads (for direct coupling to a DUT).

PSC Connectors
PSC denotes a precision slotless connector. Precision slotless connectors are metrology
grade connectors that have better electrical performance, better repeatability, and are
more durable than slotted connectors.
Clarifying the Terminology of a Connector Interface
In this document and in the prompts of the PNA calibration wizard, the gender of cable
connectors and adapters is referred to in terms of the center conductor. For example, a
connector or device designated as 1.85 mm –f– has a 1.85 mm female center conductor.
8510-series , 872 x , a nd 87 5x ON LY: In contrast, during a measurement calibration, the
network analyzer softkey menus label a 1.85 mm calibration device with reference to the
sex of the analyzer’s test port connector—not the calibration device connector. For
example, the label SHORT(F) refers to the short that is to be connected to the fem a le test
port. This will be a male short from the calibration kit.
Table 1-1 Clarifying the Sex of Connectors: Examples
Terminology Meaning
Short
–f–
Short (f) Male short (male center conductor) to be connected to female port
A connector gage is referred to in terms of the connector that it measures. For instance, a
male connector gage has a female connector on the gage so that it can measure male
devices.

Incoming Inspection
Verify that the shipment is complete by referring to Table 4-1 on page 4-4.
If the case or any device appears damaged, or i f the shipment is incompl ete, not ify Agilent.
See “Contacting Agilent” on page 4-3. Agilent will arrange for repair or replacement of
incomplete or damaged shipments without waiting for a settlement from the
transportation company.
When you send the cable set to Agilent, include the following information:
• your company name and address
• the name of a technical contact person within your company, and the person’s complete
phone number
• the model number and serial number of the cable set

General Information
Preventive Maintenance
• the part number and serial number of the device
• the type of ser v i ce re q u i red
•a detailed description of the problem
Preventive Maintenance
The best techniques for maintaining the integrity of the cables include:
• routine visual inspection
• cleaning
• proper gaging
• proper connection techniques
• proper storage
All of the above are described in Chapter 3. Failure to detect and remove dirt or metallic
particles on a mating plane surface can degrade repeatability and accuracy and can
damage any connector mated to it. Improper connections, resulting from center conductor
values being out of limits (see Table 2 on page 2-4), or from bad connections, can also
damage cable connectors.
Replaceable Parts
See Table 4-1 on page 4-4 for a complete list of cable set contents and their associated part
numbers (you can order a single cable rather than the entire cable set), and for
recommended items not included with the cable set. Refer to “Contacting Agilent” on
page 4-3 for information about communicating with Agilent.

Center Conductor Pin Depth
Center conductor pin depth is the distance the center conductor mating plane differs from
being flush with the outer conductor mating plane. See Figure 2-1 The pin depth of a
center conductor can be in one of two states: either protruding or recessed.
Protrusion is the condition in which the center conductor extends beyond the outer
conductor mating plane. This c ondition will indi cate a pos itive value on the c onnector gage.
Recession is the condition in which the center conductor is set back from the outer
conductor mating plane. This condition will indi cate a negative value on the connector
gage.
