3 Configure the function generator output channel as follows:
– Output load: High-Z load
– Output polarity: Normal
– Waveform function: Sine wave
– Amplitude unit = Vrms
– Amplitude offset = 0 V
4 Configure the frequency counter input channels as follows:
– If frequency counter model is 53220A, set SCPI language mode: 53132A
–Impedance: 1 MΩ
– Low pass filter: ON
– Input coupling: DC
– Level at center of hysteresis window: 0 V
– Trigger level percentage of signal peak-to-peak range: 50%
– Reference timebase: Internal reference
– Measurement function: Channel 1 frequency
– Frequency measurement start arm mode: Immediate
– Frequency measurement stop arm mode: Timer
