Tektronix 3A6 - Dual Trace Amplifier 196310 MHz 10mV/div to 10V/div in 10 Steps antiquated
The 3A6 Amplifier is a general-purpose, dual-trace plug-in unit designed for use in the Types 561B, 564B and 565 Oscilloscopes. The Type 3A6 features two separate channels with identical characteristics. It can be operated in any one of five modes for a variety of single and dual-trace displays. Two Type 3A6's can be used for X-Y curve tracing, but without synchronized switching or channel pairing. BANDWIDTH DC to 10Hz at 3dB down. AC-coupled low-frequency response is 2Hz, 0.2Hz with 10X probe. RISETIME Approximately 35ns. DEFLECTION FACTOR 10mV/div to 10V/div in 10 calibrated steps, 1-2-5 sequence; accurate within 3%. Uncalibrated, continuously variable between steps and to approximately 25V/div. INPUT RC 1 megohm paralleled by approximately 47 pf. MAXIMUM INPUT VOLTAGE 600V combined DC + peak AC. OPERATING MODES Channel 1 only (polarity of Channel 1 can be changed to provide 180° inversion); Channel 2 only; Alternate -- Channel 1 and 2 switched electronically on alternate sweeps; Chopped -- successive 4µs (approx) segments of each channel are displayed at an approx. 135KHz rate per channel (chopped transient blanking is provided); Added -- outputs of CHannel 1 and 2 added algebraically. INTERNAL TRIGGER SIGNAL Selectable from the output of Channel 1 only or from the combined output of the unit. Triggering from Channel 1 only permits viewing the true relationship between two signals when operating the unit in either alternate or chopped mode.Tektronix 3B3 - Time Base 196310 MHz .5us/div to 1s / div in 20 Steps antiquated
The 3B3 - Time Base Delayed and normal triggering to 10 Mhz. Single sweep operation. Time Base .5us/div to 1s / div in 20 steps. X5 Magnifier. Delay Time .5us/div to 1s / div in 1-2-5 sequence. The Type 3B3 Time Base Unit is a plug-in time base generator designed for use with the Tektronix Types 561A, 561B, RM561A, 564, 567, and RM567 Oscilloscopes. The Type 3B3 provides normal or delayed sweeps at 20 calibrated rates from 0.5 microseconds per division to 1 second per division. In delayed sweep operation, the Type 3B3 gives continuous calibrated sweep delay from 0.5 microsecond to 10 seconds after receipt of a triggering impulse. SWEEP RATES Both normal and delayed sweep rates from 0.5 microsecond per division to 1 second per division in 20 calibrated steps. A variable control provides uncalibrated sweep rates between steps and also extends the slower rate to approximately 2.5 seconds per division. Calibrated sweep rates for both normal and delayed sweeps are typically within 1%, and in all cases within 3% of the TIME/DIV. and DELAY TIME RANGE switch settings. SWEEP MAGNIFICATION The display can be magnified 5 times, extending both the normal and delayed sweep rates to 0.1 microsecond per division. Sweep rate accuracy with the 5X magnificiation remains within 5% of the TIME/DIV. and DELAY TIME RANGE switch settings. SWEEP DELAY The calibrated sweep delay is continuously variable from 0.5 microsecond to 10 seconds. Delay accuracy is 1% of full scale reading, and delay time linearity is within 0.2% of full scale from 5 microseconds to 2 seconds of delay. Time jitter is less than 1 part in 20,000 of the maximum available delay interval. SINGLE SWEEP All modes of operation can be displayed as a single sweep for photographic recording.
