HP 437B Power Meter

The HP 437B is a low-cost, high performance, single-channel,
programmable, average Power Meter compatible with the HP 8480
family of thermocouple and diode power sensors. Depending on which
Power Sensor is used, the HP 437B can measure from —70 dBm
(100pW) to +44 dBm (25W) at frequencies ranging from 100 KHz

to 50

GHz.

Designed for ATE systems and demanding benchtop measure­ments, the HP 437 B Power Meter makes fast, accurate and reliable
average power measurements. Only 3 1/2 inches high and half rack
wide, the HP 437B minimizes the use of critical rack space in ATE
systems. The advanced plastics technology used in the HP 437B cabi­net combines the light weight of plastic with the shielding effective­ness of metal, making the HP 437B the only power meter to meet
MIL-STD-461C EMI specifications.

A modern and flexible feature set makes this meter easy to use in
any application:

Automatic calibration and zeroing.

Frequency entry instead of Cal Factor.

Ten pre-loaded sensor Cal Factor versus frequency tables.

Selectable resolution to 0.001 dB.

Offset entry in dB.

Duty cycle entry for a convenient peak power representation of the

measured average power.

Ten store/recall registers.

HP-IB is standard.

Optional analog meter (H36).

With a measurement speed twice as fast as that of the industry­standard HP 436A, powerful programming capability, state-of-the­art accuracy and exceptional reliability, the HP 437B lets you mea­sure your test signal with speed, precision and confidence.

HP 70100A Power Meter Module
(Modular Measurement System)

The HP 70100A is a full-feature single channel power meter mod­ule for the Modular Measurement System (see page 115). It has all
the capability of the HP 437B Power Meter in an l/8th rack-width
module. The HP 70100A features the same modern and flexible fea­ture set as the HP 437B, the same state-of-the-art accuracy and is
also fully compatible with the HP 8480 series of power sensors.
