MODEL 650A TEST OSCILLATOR
FREQUENCY RATING
FREQUENCY RANGE: 10 cps to 10 MC
FREQUENCY DIAL
CALIBRATION : 1 to 10
RANGES: XlR 10 to 100 cps
x10m 100 to 1000 cps
XlKC 1 to 10 KC
X 1 OKC 10 to 100 KC
XlOOKC 100 to 1000 KC
X1M 1 to 10 MC
FREQUENCY RESPONSE : fl db from 10 cps to 10 MC at rated output.
FREQUENCY STABILITY: t2% from 10 cps to 100 KC and f3% from 100 KC to 10 MC.
Includes calibration error, warm-up drift, and line voltage
variations.
POWER OUTPUT RATING
POWER OUTPUT: 15 milliwatts into a 600 ohm resistive load.
3 volt output signal
600 ohm source impedance.
6 ohm source impedance is available with the voltage divider
(65A-16D Output Cable).
DISTORTION: Less than 1% from 20 cps to 100 KC and approximately 5% from
100 KC to 10 MC.
HUM LEVEL: Less than . 5% of the maximum attenuated signal level.
OUTPUT MONITOR A vacuum tube voltmeter monitors the level at the input to the
attenuator in volts and db when the instrument is properly
terminated.
Zero db - 1 mw in 600 ohms.
Accuracy is +5% of full scale reading.
Meter scales: 0-1 volt; 0-3 volt; -12 to t2 dbm.
OUTPUT ATTENUATOR The output level is attenuated 50 db in 10 db steps. The attenu-
ator when used with the AMPLITUDE control provides a con-
tinuously variable output voltage from t12 dbm to -50 dbm that
is from 3 volts to 3 millivolts.
Low level sources down to 30 microvolts may be provided by
using the 65A-l6D Output Cable (voltage divider).
ATTENUATOR ACCURACY: fl db when the instrumentis workinginto 600 ohms resistive load.
