HI,
I have a oscilloscope calibrator for 300 Euros, 20 Euros shipping to most EU country's.
Three Squarewave Output Modes
10Hz to 1MHz
Direct Readout of Oscilloscope Deflection Error
5mA calibration current loop for current probe calibration
Amplitude Calibration Mode
Period: fixed at approx. 1 ms or dc
Amplitude: 200µV p-p to 100V p-p
Pulse Modes
Period: 1µs to 10ms in decade steps
High Amplitude Output
Rise Time: unterminated: 100ns or less. Terminated into 50ohms: 10ns or less
Fast-Rise Outputs
Rise-Time (Terminated into 50 ohms): < 1.0ns
Polarity: simultaneous positive and negative going
