. BK PRECISION ® INSTRUCTION MANUAL MODEL 2190B 100 MHz DUAL-TRACE OSCILLOSCOPE BK PRECISION ®. TEST INSTRUMENT SAFETY WARNING Normal use of test equipment exposes you to a certain amount of danger from electrical shock because testing must often be performed where exposed high voltage is present. An electrical shock causing 10 milliamps of current to pass through the heart will stop most human heartbeats. Voltage as low as 35 volts dc or ac rms should be considered dangerous and hazardous since it can produce a lethal current under certain conditions.

FEATURES AUTO Sweep X Y Operation Selectable AUTO sweep provides sweep without trig- Channel 1 can be applied as horizontal deflection ger input, automatically reverts to triggered sweep (X-axis) while channel 2 provides vertical deflection operation when adequate trigger is applied. SPECIFICATIONS CRT: HORIZONTAL AMPLIFIER Type: 6-inch rectangular with integral graticule, (Input through channel 1 input) P31 phosphor. X−Y mode: Display Area: 8 x 10 div (1 div = 1 cm). CH 1 = X axis. CH 2 = Y axis. Accelerating Voltage: 12 kV.
SPECIFICATIONS Trigger Coupling: Output Impedance: Approximately 50 ohms. AUTO: Sweep free-runs in absence of Frequency Response: 20 Hz to 100 MHz, 3 dB. Suitable trigger signal. Intensity Modulation NORM: Sweep triggered only by adequate Input Signal: TTL level, intensity increasing with trigger signal. CONTROLS AND INDICATORS 15 28 Fig.
