1 General Information The Hewlett-Packard 85133E/F flexible test port return cables (Figure l-l) are designed for use with HP 8510 network analyzer tests sets that have male NMD-2.4 mm test ports (such as the HP 8516 and 8517). The Cables HP 85133E This is a single cable. Use it when a DUT (device under test) is connected, with the appropriate adapter, directly to the test set test port (see Figure l-la). HP 85133F This is a set of two cables; each is shorter than the HP 85133E cable.
Connector Designators NMD Connectors NMD denotes a connector, developed at Hewlett-Packard’s Network Measurements Division, that has larger than standard coupling threads (for greater stability). NMD connectors are used on test ports, test port adapters, and test port cables. Female NMD connectors are used on the test set end of adapters and cables, and cannot be connected to standard male 2.4 mm connectors.
T C- Handling and Storing Cables Handle cables carefully, and inspect all connectors before you make a connection. When not using a cable, store it in a way that gives it maximum protection. D Keep connectors clean. 1 Do not touch connector mating plane surfaces. Natural skin oils and microscopic particles of dirt are easily transferred to a connector interface, and are very difficult to remove. l Do not set cable connectors contact-end down on a hard surface.
= Discharge static electricity from a device before connecting it: touch the device briefly (through a resistor of at least 2 MQ) to either the outer shell of the test port, or another exposed ground. This discharges static electricity and protects test equipment circuitry. Replaceable Parts l-4 Genefal Information See Chapter 4 for information on ordering replacement cables (you can order one or the other of the cables in the cable set), and for recommended items not included with the cables.

Press MENUS (a) and use the front panel knob or the numeric keypad to set the marker to the closest point to the first frequency listed in the test record at the end of this chapter. 18. Divide the values shown on the analyzer by two and record this value in the test record. The value shown on the analyzer represents an out-and-back path of the signal, which is twice the cable insertion loss 19.

. C- A Connecting and Disconnecting Cables The most common cause of measurement error is poor connections. Remember d Good connections require a skilled operator. Instrument sensitivity and coaxial connector mechanical tolerances are such that slight errors in operator technique can have a significant effect on measurements and measurement uncertainties. Remember .c After you perform a calibration, move the test port return cables as little as possible.
Connecting a Cable to a Test Port 1. Ground yourself and all devices (wear a grounded wrist strap, and work on a static mat). 2. Visually and mechanically inspect the connectors. 3. E necessary, clean the connectors. 4. Carefully align the connectors. The male connector center pin must slip concentrically into the contact fingers of the female connector. 5. Push the connectors straight together. Do not twist or screw them together. As the center conductors mate, there is usually a slight resistance.
c Disconnecting a Cable From a Test Port Note 3 A avoid laterztl (bending) force on the connector mating plane surfaces. -~-- -_ ~ ~-- 1. Using the spanner wrench, hold the cable stationary (see Figure A-1 for wrench placement). 2. Using a 20 mm (8 in-lb) torque wrench, loosen the test set nut. 3. Complete the disconnection by hand, turning only the connector nut. Caution tl Do not twist one connector out of the other (like removing a light bulb).
8. For a Male Cable Connector: Using a 20 mm torque wrench, rotate the connector nut on the cable (see Figure A-2). USE 20mm TORQUE WRENCH HERE < USE 5116” TORQUE WRENCH HERE Figure A-2. Where to Position Wrenches to Connect a 2.4 mm Connector to a DUT 9. For a Female Cable Connector: --Y Hand tighten the 5/16 inch nut on the DUT. Using a 5116 inch torque wrench, rotate the DUT connector nut onto the female cable connector (see Figure A-2).
