fast var persist 5500 Div/μs 300 Div/μs
fast bistable 776 Div/μs 50 Div/μs
var persist 12 Div/μs 2 Div/μs
bistable 0.2 Div/μs 0.03 Div/μs
Storage time >30 s in variable persistence modes, >30 minutes in bistable modes (typically hours)
CRT 8×10 Div @ 0.9 cm/Div, 154-0745-00 with P31 phosphor; 154-0780-00 in S/N B020000 and up; 10 kV acceleration (12 kV in reduced scan modes)
Calibrator 40 mV/400 mV/4 V into >100 kΩ; 4 mV/40 mV/400 mV into 50 Ω; 1 kHz
Power 90-132 V or 180-250 V, 215 W; Fan, thermal cut-off switch
Weight 17 kg (37.5 lb)

Options

  • Option 1: Eliminates the readout system and probe power connectors.
  • Option 2: Adds X-Y Delay compensation network.
