9-2. Rack Mount Kit
The Y5537 rack mount kit provides all the hardware necessary to mount the 5500A on
slides in a 24-inch (61 cm) equipment rack. Instructions are provided in the kit. (To rack
mount the 5725A Amplifier, order kit Y5735.)
9-3. IEEE-488 Interface Cables
Shielded IEEE-488 cables are available in three lengths (See Table 9-1). The cables
attach to the 5500A to any other IEEE-488 device. Each cable has double 24-pin
connectors at both ends to allow stacking. Metric threaded mounting screws are provided
with each connector. Appendix D shows the pinout for the IEEE-488 connector.
9-4. RS-232 Null-Modem Cables
The PM8914/001 and RS40 null modem cables connect the 5500A SERIAL 1 FROM
HOST port to a printer, video display terminal, computer, or other serial device
configured as DTE (Data Terminal Equipment). Appendix D shows the pinouts for the
serial connectors.
9-5. RS-232 Modem Cables
The 943738 modem cable connects the 5500A SERIAL 2 TO UUT port to a unit under
test serial port (with DB-9 male connector). Appendix D shows the pinouts for the serial
connectors.
9-6. 5500A/LEADS
The optional test lead kit, 5500A/LEADS, consists of four high-voltage safety leads (red,
black, white, yellow), thermocouple extension wires, thermocouple miniconnectors, and
thermocouple measuring “beads.”
9-7. 5725A Amplifier Accessory
The Fluke 5725A Amplifier is an external unit operating under 5500A Calibrator control
to extend the volt/hertz and voltage compliance capability of the calibrator. The
amplifier adds the following capabilities to the calibrator with no compromise in
accuracy:
• Frequency limits at higher voltage increase to 100 kHz at 750 V, 30 kHz at 1100 V.
• Load limit increased to 70 mA for frequencies above 5 kHz
• Capacitive drive increases to 1000 pF, subject to the maximum output current.
A separate set of binding posts on the front panel of the 5725A supplies extended
capability. Since most meters have a separate input terminal for the high current ranges,
this eliminates the need to change cables during a procedure.
