Models l1049A, l1050A, l1051A Thermal Converters
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
1l049A,
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.
