Nbs type ii bolometer bridge and reference generator


Description : NBS TYPE II Bolometer Bridge and Reference Generator. Bolometer Bridge and Reference Generator.
NBS Type II Power Measurement System, , consists of two
units: a self-balancing bolometer bridge, and a reference voltage generator.
The bridge is a self-continued unit, but the reference generator draws its
power from the bridge and can only be used with it or some other external power
b. The bridge is designed to measure microwave or high-frequency power in
conjunction with an external bolometer mount (either a thermistor or a
barretter) and some means of accurate voltage measurement.
voltage generator may be used for this purpose, although this does not
generally result in the best accuracy for RF power levels less than about 80%
Use of the reference voltage generator as a
stable voltage source in conjunction with an external voltmeter produces the
This technique is particularly important at low
power levels, i.e., less than 10 milliwatts.
c. The reference generator is also designed to be used as a precision
