Tektronix TEK 2246A 100 MHz portable Oscilloscope

The TEK 2246 is a 100 MHz, four-channel, dual-sweep, portable Oscilloscope for general-purpose use.
A microprocessor-based operating system controls most of the functions in the instrument, including
a fully integrated menu-driven voltage and time measurement system with cursors (on-screen readout).
Alphanumeric CRT readouts of the vertical and horizontal scale factors are displayed on the bottom
of the large, bright screen (8 cm x 10 cm/16 kV acceleration voltage).

Vertical deflection:
- Deflection factor CH1/CH2: 2 mV/cm to 5 V/cm in 11 ranges
- Deflection factor CH3/CH4: 0,1 V/cm and 0,5 V/cm
- Rise time: < 3,5 ns Horizontal deflection: (single, dual, delayed sweep)
- Sweep rate: 0,5 s/cm to 20 ns/cm; with 10x magn. up to 2 ns/cm
- Delayed sweep: 5 ms/cm to 20 ns/cm; with 10x magn. up to 2 ns/cm

Lots of trigger modes. XY-operation up to 3 MHz.
