  • Notes
  • A most versatile instrument which combines a 0.001 Hz to 2MHz function generator with a 7W DC coupled power amplifier, an op-amp, sweep ramp generator and 3 DC power supplies. Inputs and outputs are quite independent or may be linked for a multitude of uses. The Function generator has variable ramp and pulse output, two levels of attenuation and may be swept over a 100: 1 range by its internal sweep ramp generator.
    The Power amplifier which extends from DC to >80kHz also doubles as a 1 amp, bi-polar or voltage controlled power supply or as a fixed +5V 1 amp supply.

    FUNCTION GENERATOR
    Range: 0.01 Hz to 1 M H z in 8 decade ranges. Plus, an additional 200kHz to 2MHz range. Uncalibrated range extends to 0.001 Hz.
    Output: 0 - 10V P-P or 0 - 5V into 600Ω
                   0 - 1V P-P or 0 -  0.5V  into 600Ω
    Functions : Sine. square, triangle, ramp and pulse.
    1: 1 to 50 : 1 ramp or pulse mark -space ratio TTL compatible output >3V into 2 TTL loads.
    Output Offset : 0 to ±5V
    Modulation : FM 1000 :1 DC coupled, with external signal.
                            AM 0 to 95% DC coupled, with external signal.
                            Sweep 100: 1 with internal sweep.
    Sweep: Linear ramp variable >5s to approximately 50ms.
    Sweeps over complete dial range down to any 10% portion of the range.

    POWER AMPLIF IER
    Frequency Response: DC to 80kHz-3dB.
    Output : 30V P-P current ± 1A P-P, constant current o/load, 7W into 15Ω

    BI-POLAR POWER SUPPLY
    Range: Continuously variable from -15V to +15V with 1A max. current at any voltage.

    +5V POWER SUPPLY
    Output : Fixed +5V Max current 1A.

    VOLTAGE/OPERATION A L AMPLIFIER
    Frequency Response: DC to 80kHz
    Gain: x 1 to x 100 continuously variable or may be switched with O/C feedback and isolated inputs: Input: 10kΩ each side or 0 .5MΩ isolated.
    Slew Rate: 4V/us .

    DUAL POWER SUPPLY
    Output: +1 to + 15V and -1 to- 15V about a common 0 line.
    May be used as + and - rails to 15V or from ± 2 to ±30V as a single supply.
    Current: 1A short circuit protected.
    Line and load regulation: <1%

    HIGH VOLTAGE SUPPLY
    Output: 0-200V, 30mA continuously variable
    AC Output: 12.6V, 1A CT (6 .3-0-6.3) fused.
