HP 209A OSCILLATOR

The 209A Oscillator is a small, lightweight, sine/square oscillator. Stable, accurate signals which can be synchronized with an external source are instantly available over a frequency range from 4Hz to 2MHz. Separate adjustable sine/square outputs are located on the front-panel. Distortion and flatness can be minimized at low frequencies by a rear-panel Low Distortion Mode switch. Sine wave output of 5 V (600-ohms); square wave output of 20 V (p-p) into 600-ohms

RANGES:

Frequency:

 4hz to 2MHz in 6 ranges

performance:

dial accuracy +/-3% or frequency setting.

flatness:

at max output into 600 ohm load:

 +/- 0.5% from 100hz to 300 KHz

 +/- 1% from 200kHz to 1MHz

 +/- 5% from 1MHz to 2MHz

below 100hz, +/- 1% in LF low distortion mode, +5/-1% in normal mode.

distortion is 0.1% from 200hz to 200kHz, degrading to 1% at the ends of the

frequency range. In LF low distortion mode, the degradation is only 0.2%

at the low end.

hum and noise: less than 0.01% of output.

output characteristics:

sine wave: 

 output voltage: 5V rms into 600 ohms, 10V open circuit. output can be

 floated up to +/- 500V peak between output and chassis ground.

 output impedance: 600 ohms

 output control: 20 dB range, continuously adjustable.

 output balance: greater than 40db below 20 kHz

square wave:

 output voltage: 20V pk-pk open circuit, symmetrical about zero. Output

 can be floated +/- 500V from chassis ground.

 rise and fall time: less than 50ns

 symmetry: +/- 5%

 output impedance: 600-900 ohms depending on setting of output control

external synchronization:

 sync impedance: 10 kohm

 sync output: sine wave in phase with output. amplitude into 1megohm

 shunted by 100pf is greater than 1.7V rms from 4hz to 50KHz, greater

 than 0.1V above 50KHz

 sync input: oscillator can be synchronized to external signal. for 5V

 rms input, sync frequency can be as much as +/- 7% away from set

 frequency. sync range is a linear function of sync voltage.

general:

 operating temperature: 0C to 55C

 storage temp: -40C to 75C

 pwer AC line 115V or 230V +/- 10%, 50 hz to 400Hz, less than 7W.
