Test and Compare
I have two oscilloscopes. An analog HAMEG HM 203-4 (20 MHz, 1982) and a digital OWON SDS1102 (100 MHz, 2021). Admittedly, the OWON is of course very handy and fits on even the most crowded desk. But the HAMEG is, of course, simply fantastic. You can't compare the two. Just as little as a Raspberry Pi and a Kaypro II.
To compare both oscilloscopes with each other (analogue versus digital), I connected both to the square-wave generator of the other device.
The OWON generates: 1 kHz at 5 V. This signal is very accurate and is shown very well by both devices.
TIMEBASE: ... 5,0 cm * 0,2 ms/cm = 1 ms ≙ 1 kHz
AMPL. I: .... 2,5 cm * 2,00 V/cm = 5 V
Test 1 OWON: 5V, 1 kHz
The HAMEG generates: ~1 kHz at 0,2 V. The manual specifically points out that the square-wave generator must not be used for time calibration. This was also confirmed in my comparison. It is not exactly 1 kHz, but only 0.893 kHz. However, this does not matter for the calibration of the HAMEG probe.
TIMEBASE: ... 5,6 cm * 0,2 ms/cm = 1,12 ms ≙ 0,893 kHz
AMPL. I: .... 2,2 cm * 0,10 V/cm = 0,22 V
Test 2 Hameg: 0,22V 0,893 kHz
Result: For an analogue oscilloscope from 1982, the result is quite good, as far as I can tell. I will do some tests with a signal generator later.
