Output Floating (switchable)
High Amplitude Stability
The HM8037 Sine Wave Generator is a high
quality sinusoidal signal source for applications
requiring high stability and spectral purity for
audio/video applications. The low distortion
factor, low noise level and excellent flatness
render this instrument suitable for measurements
of linear or non-linear distortions in high-grade
audio systems. Simplicity of operation of the
HM 8037 is another important feature of this
instrument.
The generator frequency can be precisely tuned
by means of the 3-digit frequency display. A
resolution as fine as 0.1Hz can be obtained in the
lower frequency range. High precision
components are used in the manufacture of this
product, in the frequency generating network
circuitry, which assures an exceptionally high
stability. The flat amplitude of ±0.2dB elimi-
nates the need of constantly monitoring the
voltage level during frequency response testing.
The output voltage of the HM8037 is adjustable
over a 60dB range for examination of sensitive
Hi-Fidelity amplifiers. The 600Ω output can be
switched from chassis (earth) to floating signal
ground, depending on user/circuitry re-
quirements. The HM 8037, in combination with
the HAMEG HM 8027 Distortion Meter, is
suitable for precision distortion measurements.
An entire test system can be created with these
two instruments, which can perform high quality
audio/video system measurements.
