Oscilloscope 211

The Tektronix 211 Oscilloscope is a single-channel, 500 kilohertz portable instrument using only solid state and integrated circuit components (except CRT) . The small size of the 211 makes it an extremely portable oscilloscope for on-location maintenance in many fields of application. The instrument is mechanically constructed to withstand the shock, vibration, and other extreme conditions associated with portability. The DC to 500 kilohertz vertical system provides vertical deflection factors from one millivolt (at reduced bandwidth) to 50 volts /division at the tip of the integral high-impedance probe. The trigger circuits provide stable triggering over the full bandwidth capabili ties of the vertical system.

The horizontal deflection system provides calibrated sweep rates from 200 milliseconds to five microseconds/division. A continuously variable sweep magnifier provides uncalibrated sweep rates to at least five times the indicated sweep rate, for a maximum sweep rate of at least one microsecond/ division. In addition, external horizontal amplifier operation provides horizontal deflection factors of one and 10 volts /division. The resultant CRT display produced by the vertical and horizontal deflection systems is presented on a 6 x 10 division graticule (each division equals 0.203 inch).

The 211 can be operated either from AC line voltage or from internal rechargeable batteries. Maximum total power consumption is two watts. The internal batteries can be recharged from the AC power line by the integral battery charger (instrument off).

Power line options:

• Standard 60 Hz, 110-126 V
• Option 1 50 Hz, 220-250 V
• Option 2 50 Hz, 90-110 V
