Accessories
A number of accessories are available from Agilent Technologies to help
you configure your analyzer for your specific applications. They can be
ordered through your local Agilent Sales and Service Office. Refer to
Table 4-1 on page 4-6 for a list of Agilent Sales and Service Offices.
RF and Transient Limiters
The HP/Agilent 11867A and 11693A RF Limiters protect the spectrum
analyzer input circuits from damage due to high power levels. The
HP 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 11947A Transient Limiter protects the spectrum 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.
50 Ω/75 Ω Minimum Loss Pad
The HP/Agilent 11852B is a low VSWR minimum loss pad that allows
you to make measurements on 75 Ω devices using an analyzer with a
50 Ω input. It is effective over a frequency range of dc to 2 GHz.
75 Ω Matching Transformer
The HP/Agilent 11694A allows you to make measurements in 75 Ω
systems using an analyzer with a 50 Ω input. It is effective over a
frequency range of 3 to 500 MHz.
RF Bridges
The HP/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 with an external signal
generator. These external directional bridges offer high directivity and
excellent port match. The 86205A operates over a frequency range of
300 kHz to 6 GHz. The 86207A operates over a frequency range of
300 kHz to 3 GHz.
