channel B 10Hz to 2.5MHz.
Sensitivity: channel A 25 mV rms to 100MHz,
75 mV p-p at minimum pulse width of 5 ns (100MHz range),
channel B 25 mV rms to 2.5MHz,
75 mV p-p at minimum pulse width of 200 ns, AC coupling.
1 Mohm nominal impedance shunted by less than 30 pF.
X1 or X20 nominal attenuation (A channel only).
Trigger level is continuously variable ?350 mV
times attenuator setting around average value of signal.
