Signal Analyzers Amplifiers and Accessories
11867A and N9355/56 Series Limiters
Protect the input circuits of spectrum analyzers, counters, amplifiers
and other instruments from high power levels with minimal effect on
measurement performance. The 11867A RF limiter (dc to 1.8 GHz)
reflects signals up to 10 W average power and 100 W peak power.
Insertion loss is less than 0.75 dB. The N9355/56 series microwave
limiters cover frequency ranges from 10 MHz to 18 GHz (N9355B/56B),
to 26.5 GHz (N9355C/56C), and to 50 GHz (N9355F), respectively. They
provide the best broadband input power protection to sensitive RF and
microwave instruments with low insertion loss. Typical limiting
threshold for the N9355 limiters is 10 dBm and that for the N9356 is
25 dBm.
11825B Impedance Matching Adapter
Impedance matching adapters are instrument grade tools used in
RF and microwave signal matching that adapt 50-ohm impedance to
75-ohm impedance or vice versa. The 11852B minimum loss adapter
is a 50
Ω
to 75
Ω
or 75
Ω
to 50
Ω
impedance converter with type-N
connectors, operating from DC to 3 GHz. Use the Agilent 11852B
Option 004 (50
Ω
type-N(f), 75
Ω
type-N(m)) for spectrum analyzers
with 50
Ω
input impedance when the 50
Ω
/75
Ω
impedance conver-
sion is required.
85024A Probe (300 kHz to 3 GHz)
In-circuit measurements are made easy with this 300 kHz to 3 GHz
probe. Input capacitance of 0.7 pF shunted by 1 M
Ω
resistance
permits high-frequency probing without adverse loading of the
circuit under test. Excellent frequency response and unity gain guar-
antee highly accurate swept measurements. High sensitivity and low
distortion levels allow measurements that take advantage of full
analyzer dynamic range.
87405B/C Preamplifiers
Agilent 87405B/C operates from the operating frequency as low as
100 MHz up to 18 GHz. They provide a low noise figure of 4.5 dB on
87405C model and 5 dB on 87405B model and gain from 24 dB. These
will improve the dynamic range and sensitivity of your test
equipment. With its convenient probe-power bias, the 87405B/C
preamplifiers are ideal use as the front end preamplifier for a
variety of Agilent instruments such as PSA, ESA, MXA, EXA, and
CSA spectrum/signal analyzers. They also come in a rugged and
portable design which will ease the use in many field applications.
As a whole, Agilent 87405B/C preamplifiers improve the overall sys-
tem performance and help reduce system errors with reliable gain
and low noise figure.

8449B Preamplifier (1 to 26.5 GHz)
This high-gain, low-noise preamplifier increases the sensitivity of
any RF/microwave spectrum analyzer for detection and analysis of
very low level signals. The improved sensitivity can dramatically
reduce measurement time.
8447A and 8447D Amplifiers
The Agilent 8447A and 8447D are low-noise, high gain amplifiers
used to improve the sensitivity of counters, spectrum analyzers, RF
voltmeters, EMI meters, power meters and other devices. They will
also increase the maximum power available from a signal generator
or sweeper.
