It has the characteristics of frequency bandwidth, many calibration parameters and extremely fast rising edge of pulse output. Can be used to calibrate the master Want technical indicators.3 Metrological performance requirements3.1 Calibration voltage DC output range and maximum allowable error. 1MΩ. (0~±200)V, ± (0.025% output 25μV); 50Ω. (0~±5)V, ± (0.025% output 25μV). Square wave output range and maximum allowable error. 1MΩ. ± (1mV~200V), ± (0.05% output 5μV); 50Ω. ± (1mV~5V), ± (0.25% output 40mV); Frequency. 10Hz~100kHz. 3.2 rising (falling) edge output Rise (fall) time. 75ps~1ns. Waveform distortion. ± 5%. Frequency range and maximum allowable error. 1kHz~10MHz, ±3×10-7. Duty cycle. 10%~90%. 3.3 time scale output Range and maximum allowable error. 0.5 ns to 5 s, ± 3 × 10 -7. 3.4 Broadband Steady Signal Source Output Range of amplitude and maximum allowable error. 5mV~5.5V (peak-to-peak), ± (2%~6%) output (calculated in sub-band). Frequency range and maximum allowable error. 0.1Hz~3.2GHz, ±3×10-7. Amplitude flatness. ± (1.5% to 6%) output (sub-band calculation). ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of JJG 278-2002_English be delivered?Answer: Upon your order, we will start to translate JJG 278-2002_English as soon as possible, and keep you informed of the progress.
