AC Power Source

The HP 85901A provides 200 watts of continuous power for field and mobile application. The
self-contained ac power source has outputs for either 115 V or 230 V and runs on its own
internal battery, an external battery, or on another 12 V dc source. Typical operating time
exceeds 1 hour for 100 watt continuous use at room temperature.
AC Probe
The HP 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 MQ
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.
Caution
Do not use dc-coupled probes on HP 8592L and HP 85933 analyzers; they may
cause damage to the spectrum analyzer input circuit.
When using a dc-coupled probe with an HP 85943, HP 85953, or HP 85963,
the spectrum analyzer must be set to ac coupling. To set the analyzer to ac
coupling,press
that AC is underlined.

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 HP 10855A preamplifier provides a minimum of 22 dB gain from 2 MHz to 1300 MHz.
n
The HP 8449B preamplifier provides a minimum of 30 dB gain from 1 GHz to 26.5 GHz.
n
The HP 8447D preamplifier provides a minimum of 25 dB gain from 100 kHz to 1.3 GHz.
n
The HP 84473 power amplifier provides a minimum of 22 dB gain from 0.1 GHz to 1.3 GHz.
n
The HP 87405A preamplifier provides a minimum of 22 dB gain from 10 MHz to 3 GHz.
n
The HP 85905A CATV 75 ohm preamplifier provides a minimum of 18 dB gain from 45 MHz
n
to 1 GHz.

Burst Carrier Trigger

For use with HP 8590 E-Series spectrum analyzers. The HP 85902A burst carrier trigger
detects the burst RF carrier of a digital communication system and provides a TTL output
trigger to synchronize a spectrum analyzer. The triggering function is especially useful when
performing time-dependent measurements used as power versus time and adjacent channel
power gated measurements. The HP 85902A is compatible with most digital communications
formats, including NADC-TDMA, E- TDMA, JDC, GSM, DCS-1800, CT2-CAI, DECT, PHP, and
CDMA.
