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
and are listed below.

50 Ohm/75 Ohm Minimum Loss Pad

The HP/Agilent 11852B is a low VSWR minimum loss pad that allows you to make measurements on 75
Ohm devices using an analyzer with a 50 Ohm input. It is effective over a frequency range of dc to 2
GHz.

75 Ohm Matching Transformer

The HP/Agilent 11694A allows you to make measurements in 75 Ohm systems using an analyzer with a
50 Ohm input. It is effective over a frequency range of 3 to 500 MHz.

AC Probe

The Agilent 85024A high frequency probe performs in-circuit measurements without adversely loading
the circuit under test. The probe has an input capacitance of 0.7 pF shunted by 1 MOhm of resistance and
operates over a frequency range of 300 kHz to 3 GHz. High probe sensitivity and low distortion levels
allow measurements to be made while taking advantage of the full dynamic range of the spectrum
analyzer.

AC Probe (Low Frequency)

The Agilent 41800A low frequency probe has a low input capacitance and a frequency range of 5 Hz to
500 MHz.

Broadband Preamplifiers and Power Amplifiers

Preamplifiers and power amplifiers can be used with your spectrum analyzer to enhance measurements
of very low-level signals.
• The Agilent 8447D preamplifier provides a minimum of 25 dB gain from 100 kHz to 1.3 GHz.
The Agilent 87405A preamplifier provides a minimum of 22 dB gain from 10 MHz to 3 GHz. (Power
is supplied by the probe power output of the analyzer.)
The Agilent 83006A preamplifier provides a minimum of 26 dB gain from 10 MHz to 26.5 GHz.
• The Agilent 85905A CATV 75 ohm preamplifier provides a minimum of 18 dB gain from 45 MHz to
1 GHz. (Power is supplied by the probe power output of the analyzer.)
• The 11909A low noise preamplifier provides a minimum of 32 dB gain from 9 kHz to 1 GHz and a
typical noise figure of 1.8 dB.
