This chapter is a dictionary reference table of front and rear-panel connectors,
front-panel keys (hardkeys), softkeys, and display annotations. With the
exception of a few front-panel keys, softkeys control all instrument functions.
This chapter is designed for quick access of information. For example, during
operation you may find a softkey or hardkey whose function is unfamiliar to
you. Note the key name, find the key in this chapter, and note the applicable
function. Some keys will have more than one function. Keys that begin with a
symbol are listed at the front of the table.

High Stability Frequency Reference. Option 1D5 offers ±0.05 ppm temperature stability from 0 to 60°C (referenced to 25°C).
Harmonic Mode. Provides measurement of second or third harmonics of the
test device’s fundamental output signal. Frequency and power sweep are supported in this mode. Harmonic frequencies can be measured up to the maximum frequency of the receiver. However, the fundamental frequency may not
be lower than 16 MHz.
Extends the maximum source and receiver frequency of the analyzer to
6GHz.
Receiver Configuration. Option 011 allows front panel access to the R, A, and
B samplers and receivers. The transfer switch, couplers, and bias tees have
been removed. Therefore, external accessories are required to make most
measurements.
75Ω Impedance. Option 075 offers 75 ohm impedance bridges with type-N
test port connectors.
Deletes Time Domain. This option
displays the time domain response of a network by computing the inverse
Fourier transform of the frequency domain response. It shows the response of
a test device as a function of time and distance. Displaying the reflection coefficient of a network versus time determines the magnitude and location of
each discontinuity. Displaying the transmission coefficient of a network versus
time determines the characteristics of individual transmission paths. Time
domain operation retains all accuracy inherent with the correction that is
active in the frequency domain. The time domain capability is useful for the
design and characterization of such devices as SAW filters, SAW delay lines,
RF cables, and RF antennas.

Accurate operation of the analyzer system can be verified by measuring
known devices other than the standards used in calibration, and comparing
the results with recorded data.
HP 85029B 7 mm Verification Kit
This kit contains traceable precision 7 mm devices used to confirm the system’s error-corrected measurement uncertainty performance. Also included is
verification data on a 3.5 inch disk, together with a hard-copy listing. A system
verification procedure is provided with this kit and is also located in the

System Cabinet
Plotters and
Printers
The HP 85043D system cabinet is designed to rack mount the analyzer in a
system configuration. The 132 cm (52 in) system cabinet includes a bookcase,
a drawer, and a convenient work surface.
The analyzer is capable of plotting or printing displayed measurement results
directly (without the use of an external computer) to a compatible peripheral.
The analyzer supports HP-IB, serial, and parallel peripherals. Most HewlettPackard desktop printers and plotters are compatible with the analyzer. Some
common compatible peripherals are listed here (some are no longer available
for purchase, but are listed here for your reference).
These plotters are compatible:
• HP 7440A ColorPro Eight-Pen Color Graphics Plotter
• HP 7470A Two-Pen Graphics Plotter
• HP 7475A Six-Pen Graphics Plotter
• HP 7550A/B High-Speed Eight-Pen Graphics Plotter
These printers are compatible:
• HP DeskJet 1200C (can also be used to plot)
• HP DeskJet 500
• HP C2170A, DeskJet 520
• HP DeskJet 500C
• HP DeskJet 540
• HP DeskJet 550C
• HP DeskJet 560C
• HP DeskJet 600, 660C, 682C, 690C, 850C, 870C, 1600C
• All LaserJets (LaserJet III and above can also be used to plot)
• HP C2621A DeskJet Portable InkJet
• PaintJet 3630A PaintJet Color Graphics Printer
• Epson printers which are compatible with the Epson ESC/P2 printer control
language, such as the LQ570, are also supported by the analyzer. Older Epson
printers, however, such as the FX-80, will not work with the analyzer.
Mass Storage
The analyzer has the capability of storing instrument states directly to its
internal memory, to an internal disk, or to an external disk. The internal
3.5 inch floppy disk can be initialized in both LIF and DOS formats and is capable of reading and writing data in both formats. Using the internal disk drive is

the preferred method, but all the capability of previous generation analyzers,
to use external disk drives, still exists with the HP 8702D. Most external disks
using CS80 protocol are compatible.
The analyzer does not support the LIF-HFS (hierarchy file system) directory
format.
CAUTION
HP-IB Cables
Interface Cables
Keyboards
External Monitors
Do not use the older single-sided disks in the analyzer’s internal drive.
An HP-IB cable is required for interfacing the analyzer with a plotter, printer,
external disk drive, or computer. The cables available are:
• HP 10833A HP-IB Cable, 1.0 m (3.3 ft.)
• HP 10833B HP-IB Cable, 2.0 m (6.6 ft.)
• HP 10833D HP-IB Cable, 0.5 m (1.6 ft.)

• HP 24542G Serial Interface Cable, 3 m (9.9 ft.)
• HP C2950A Parallel Interface Cable, 2 m (6 ft.)
A keyboard can be connected to the analyzer for data input, such as titling
files. The HP C1405B Option ABA keyboard, with the HP part number C140560015 adapter, is suitable for this purpose. Or, the analyzer is designed to
accept most PC-AT-compatible keyboards with a standard DIN connector.
Keyboards with a mini-DIN connector are compatible with the HP part number C1405-60015 adapter.
The analyzer can drive both its internal display and an external monitor simultaneously. One compatible color monitor is the HP 35741A/B. (It is no longer
available for purchase, but is listed here for your reference.)
External Monitor Requirements:
• 60 Hz vertical refresh rate
• 25.5 kHz horizontal refresh rate
• RGB with synchronization on green
• 75 ohm video input impedance
• video amplitude 1 V p-p (0.7 V= white, 0 V= black, –0.3 V= synchronization)
