Supply 7116C automatic sweep oscillator

? Low distortion sine wave scanning? Digital display voltmeter and frequency meter? Logarithmic sweep? To learn and use? Built-in amplifier and output protection circuit? Voltage values ??are coarse and fine adjustment setting button? Excellent reliability sex? Fo value can be manually tested, the frequency can also fine-tune the technical parameters of the frequency range 20Hz ~ 20 kHz frequency error ≦ ± 0.25dB, 20Hz ~ 20 kHz. Scan Mode Manual, automatic logarithmic sweep sine wave distortion ≦ 0.15%, (20Hz . ~ 20 kHz) the sweep time of 0.3 to 40 seconds adjustable frequency meter 4-digit display Resolution 1 Hz Accuracy ± 1 Hz ≧ 2 Ω load impedance voltmeter 3-digit, autoranging low range:...? 0.000v ~ 3.300v Resolution:. 0.001v High Range: 3.300v ~ 40.00v Resolution:. 0.01v precision:. ± 0.6% output voltage adjustment range 8 Ohms load: 7116C (20W) 0 ~ 12.6 V 7116C (60W) 0 ~ 22.0 V 7116C (100W) 0 ~ 28.3 V 7116C (200W) 0 ~ 40.0 V 4 Ohms load: 7116C (20W) 0 ~ 9.0 V 7116C (60W) 0 ~ 15.5 V 7116C (100W) 0 ~ 20 V 7116C (200W) 0 ~ 28.3 V Frequency range: 20 Hz ~ 3 kHz, 4 files: a 16 Hz ~ 80 Hz b 54 Hz ~ 270 Hz c 180 Hz ~ 900 Hz d 600 Hz ~ 3 kHz Fo determination........ error ≦ ± 1% or ± 1 Hz.
