Specifications; Calibration Accuracy - HP 11049A Operating And Service Manual

l1050A
Hewlett-Packard Thermal Converters are true rms indicators,
yielding a dc output voltage proportional to the temperature
rise resulting from the input power. The Models
1l050A and 1l051A offer an exceptionally flat response and
nearly constant impedance over a wide frequency range. These
characteristics make the thermal converters ideal to check the
response of precision ac voltmeters, oscilloscopes and amplifiers.
