The Tektronix 2337 is a ruggedized portable dual-channel, 100 MHz analog scope. An A Ext connector (external signal to the A Trigger Generator) on the front panel, B Ext connector (external signal to the B Trigger Generator) on the front cover, and External Z-Axis connector at the rear round out its connectivity. The front cover also has a 3½ digit LCD for delta time (disconnects DMM from LCD readout), DC (up to 500 V), RMS AC (up to 350 V), and Ω (up to 20 MΩ) measurements, and B Trigger function.
Vertical controls were by way of calibrated deflection factors on CH 1 or CH 2 inputs through AC, DC, or GND coupling. The vertical mode selections are CH 1, ALT, CHOP (~275 kHz), ADD, CH 2, AUTO, X-Y, TRIG VIEW, or BW LIMIT (20 MHz). Horizontal deflection is controlled by either the calibrated A or B Sweep Generators, or Alternate between the two of the A, and B Delayed Sweep.
Trigger sources may be VERT MODE, CH 1, CH 2, LINE, EXT, and EXT ÷ 10. Trigger coupling can be AC, LF REJ, HF REJ, or DC, and can be controlled by amplitude level and slope type. The Trigger Modes may be set to AUTO, NORM, and SGL SWP.
