The Tektronix Type 422 Oscilloscope is a transistorized portable oscilloscope designed to operate in a wide range of environmental conditions. The light weight and small size of the Type 422 allow it to be easily transported, while providing the performance necessary for accurate measurements. The dual-channel, DC to 15 MHz vertical system provides calibrated deflection factors from 0.01 to 20 volts/division (0.001 volts/division minimum, Channel 2 only with reduced frequency response). The trigger circuits provide stable· triggering over the full range of vertical frequency response. The horizontal circuits provide a maximum sweep rote of 0.5 microseconds/division (0.05 microseconds/division using X10 magnifier). A detachable power supply section allows the instrument to be powered from a variety of power sources. With the Type 422 AC Power Supply (016-0072-00) the instrument can be operated from an AC power source. The Type 42? AC- DC Power Supply (016-0073-00) provides operation from either AC or DC power sources or internal batteries. Information in this manual applies to the Type 422 Indicator only.
