Introduction
Purpose and Function
The 1830A power meter is designed for thermistor based RF power sensors which are universally
recognized as the most accurate means to measure and transfer RF power. The TEGAM Model
1830A is designed to replace the HP432 while further reducing uncertainties and accommodate a
wider variety of RF power sensors. It combines a modern DC substitution bridge with a 6.5 digit
measurement system to provide consistent normalized RF power readings manually or
automatically.
Key functions of the 1830A:
•
Replaces the HP432 RF Power Meter
•
Compatible with thermistor power sensors from: Agilent (HP), TEGAM,
Weinschel, Hughes, General Microwave, Millitech
•
Supports 100 Ω and 200 Ω
thermistors
•
Integrates bridge balancer and power meter into one package
•
Four digit calibration factor resolution
•
Full remote programmability
•
Heater control for ovenized sensors
Capabilities
There are many thermistor based RF power sensors available. The Model 1830A is designed to
bias either 100 Ω or 200 Ω mounts and has dual bridges for balancing both RF sense and
compensation thermistors such as contained in the Agilent 478A and 8478B. It also is works with
the Agilent 486A series of waveguide sensors and includes a heater circuit for all TEGAM and
Weinschel ovenized thermistor mounts.
