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.
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 M Ω 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.
The Agilent 41800A low frequency probe has a low input capacitance and a frequency range of 5 Hz to
500 MHz.
Agilent E1779B Battery Pack
The E1779B 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 E1779B Battery Pack User’s Guide for more
information.
NOTE Agilent recommends a two person lift when using this instrument with the model 1779B
battery pack attached.
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 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.
Carrying Strap
The E4401-60028 carrying strap comes with Options AYT and AYU. It can also be ordered separately
and used with Agilent EMC analyzers.
Close Field Probes
11940A close field probe (9 kHz - 30 MHz)
11941A close field probe (30 MHz - 1 GHz)
