Oscilloscope 2236

The Tektronix 2236 100 MHz 2-Ch Dual Trace Oscilloscope
has a counter/ timer/ DMM, integrated into the scope's vertical, horizontal and trigger systems. The Tek 2236 provides easy, accurate, and versatile measurements through microprocessor-driven waveform analysis. Autoranged and autoaveraged counter/timer measurements are made on the signal triggering the A sweep, or in gated modes on the signal triggering the B sweep. Autoranged DMM measurements are made through floating DMM side inputs and up-range at 5000 counts. Channel 1 voltage measurements made on Channel 1 signal include: dc, relative dc, relative and true ac RMS voltage. Self-testing includes power-on and user interactive routines. Characteristics. Vertical System: Bandwidth (- 3dB) and Rise Time: 100 MHz and 3.5 ns, derated to 90 MHz at 2 mV/div and outside 0°C to +35°C. Bandwidth Limit: 20 MHz. Deflection Factor: 2 mV to 5 V/div. Display Modes: CH 1, CH 2, CH 2 Invert, Add, Alternate, Chop (500 kHz). Horizontal System: Sweep Rate: A Time Base: 0.05 /µs to 0.5 s/div. 10X Mag: 5 ns/div. B Time Base: 0.05 /µs to 50 ms/div. 10X Mag: 5 ns/div. Delay Time Range: Continuously variable with 10-turn control. Display: Monochrome CRT - 8 cm x 10 cm.
