Agilent 423 and 8470B Detectors vi

Description

The Agilent Technologies 423B and 8470B detectors are 50 Ω (nominal) Schottky diode devices designed for measurement use in coaxial systems.

Features • The instruments convert the RF power levels applied to the 50 Ω input

connector into proportional values of dc voltage.

• The instruments measure re la ti ve power up to 200 mW and have a BNC

female connector for the ou tput j ack whi ch all ows the detec ted out put t o

be connected to a SWR meter.

• The output voltage polarity is negative, unless Option 003 is selected.

• The frequency range of the 423B is 10 MHz to 12.4 GHz.

• The frequency range of the 8470B is 10 MHz to 18 GHz.

• AM modulation can be detected up to about 1 MHz.

Options The 423B and 8470B detectors are available with the following

non-exclusive options.

Option 001: Matched pair of detectors

Option 002: Furnished with matched load resistor for optimum

square law characteristics Option 003: Positive polarity output Option 012: Furnished with stainless steel type-N male

connectors (8470B only)

Connectors • The mating RF input connectors used with the 423B and 8470B

Option 012 must be type-N female connectors which comply with U.S. military standard MIL-C-39012.

• The 8470B (standard) RF input connector must be an 7-mm connector.

• The mating output connector for the 423B and 8470B must be a BNC

male.
