Test Oscillator
Information
The Hewlett-Packard Model 651B Test Oscillator is a wide
range capacitance-tuned Oscillator covering a frequency
range from 10 Hz to 10 MHz. The Oscillator has a stable
sine-wave output signal that is adjustable from 10
microvolts to 3.16 volts into 50 or 600 ohms. The Model 651B
Test Oscillator is shown in Figure 1-1 and the
specifications are given in Table 1-1. This manual is
written for the standard Model 651B Test Oscillator; refer
to paragraph 1-7 for differences between the standard
instrument and Options 01 and 02.
1-3. Two output impedances are provided at front panel
output connectors. The 600 ohm connector provides an output
with an impedance that is compatible with transmission lines
and many distribution systems. The 50 ohm connector provides
an output where a low - source impedance is desired.
1-4. The Model 651B Test Oscillator output voltage is
constantly monitored at the input of the attenuator by an
internal voltmeter. The voltmeter has two scales for RMS
voltage readings and a dBm scale referenced to 1 milliwatt
into 50 ohms. The OUTPUT ATTENUATOR, in conjunction with the
AMPLITUDE control, provides a monitored output of desired
level when matched into a 50 or 600 ohm load.
