Informação

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.
