Sir, the maximum sampling rate is 1GSa/s.
The time base is smaller, the sampling rate is greater.
When you open only one channel, the maximum sampling rate is 1GSa/s.
When you open two channels, the maximum sampling rate is 500MSa/s.
When you open three or four channels, the maximum sampling rate is 250MSa/s.
I need some help with 6254bc oscilloscope which seems to have corrupted eeprom attached to Cypress microcontroller. I have replaced it but I still need firmware for this chip, is there anyone who could help?
