The following four models are available:
Agilent E1779A Battery Pack
The E1779A is a battery pack that will power an Agilent analyzer for 80 to 114 minutes,
depending on the options installed in the analyzer. Refer to the E1779A Battery Pack
User’s Guide for more information.
Parallel Interface Cable
For use with Option A4H and 1AX. A 36-pin to 25-pin male-to-male 2 meter cable can be
used to connect supported printers to an analyzer. This cable must be IEEE-1284
compliant.
Printer
For use with Option A4H or 1AX. The DeskJet personal printers provide black and
white or color printing for another form of permanent records of your test results. The HP
LaserJet series printers are also compatible. The printers connect to the parallel interface
installed on the analyzer with either Option A4H (standard) or 1AX.
RF and Transient Limiters
The Agilent 11867A and 11693A RF Limiters protect the analyzer input circuits from
damage due to high power levels. The 11867A operates over a frequency range of dc to
1800 MHz and begins reflecting signal levels over 1 mW up to 10 W average power and
100 watts peak power. The 11693A microwave limiter (0.1 to 12.4 GHz, usable to 18 GHz)
guards against input signals over 1 milliwatt up to 1 watt average power and 10 watts
peak power.
The Agilent 11947A Transient Limiter protects the analyzer input circuits from damage
due to signal transients. It specifically is needed for use with a line impedance
stabilization network (LISN). It operates over a frequency range of 9 kHz to 200 MHz, with
10 dB of insertion loss.
RF Bridges
The Agilent 86205A 50 Ω RF bridge and 86207A 75 Ω RF bridge can be used to make
reflection measurements using an analyzer with tracking generator Option 1DN or 1DQ or
Table 5-2.
