Type Tektronix B Plug-In Unit Don't have the means to test the item. The Item comes with a Full size Manual and A small introduction manual for the unit( The Tiny white manual in pictures) The Item is being sold as is. For parts or not working Bandwidth - Up to 20 MHz Risetime - down to .018?sec .005 V/CM to 20 V/CM Tektronix Type B Plug-In. General The Type B Plug-In Unit is a wide-band, high gain calibrated preamp, designed for use with Tektronix Type 530-, 540- and 550 Series Oscilloscopes. The unit contains a dc amplifier similar to that in the Type A Unit preceded by a wide-band ac amplifier. Type B Specifications Instrument Used With Transient Response .05 v to 20 v/vm/td> Transient Response .005 v to .02 v/cm Risetime Pass Band* Risetime Pass Band* 541, 541A, 543 545, 545A, 555 .018?sec DC - 20 MHz 2 Hz - 20 MHz ac .03?sec 3 Hz - 12 MHz 551 .02?sec DC - 19 MHz .03?sec 3 Hz - 12 MHz 531, 531A, 533, 535, 535A .035?sec DC - 10 MHz 2 Hz - 10 MHz ac .04?sec 3 Hz - 9 MHz 532 .07?sec DC - 5 MHz 2 Hz - 5 MHz AC .07?sec 3 Hz - 5 MHz * Down not more than 3 db at indicated limits. Plug-In Amplifier Risetime at .05 to 20 v/cm - .01 ?sec. Risetime at .005 to .02 v/cm - .03 ?sec. Deflection Factor: .05 v/cm to 50 v/cm dc .005 v/cm to 50 v/cm ac. Signal Inputs - Two signal inputs with more than 60 db isolation. Step Attenuator: Twelve positions, calibrated, from .005 v/cm to 20 v/cm, accurate within 3% when set on any one step. Maximum Allowable Combined DC and Peak AC Input Voltage - 600 V. Input Impedance: - 1 megohm, 47 pf. With P410 probe - 10 megohms, 11 pf. With P510 probe - 10 megohms, 15 pf. With P6000 probe - 10 megohms, 11.5 pf - 14.5 pf. FUNCTIONS OF CONTROLS AND CONNECTORS INPUT A INPUT B Separate UHF coax connectors to the preamp by way of the INPUT SELECTOR switch. INPUT SELECTOR Four-position switch to select either of the two inputs and the type of input coupling. DC BAL Screwdriver control to adjust the amplifier balance so the trace does not shift as the VARIABLE control is rotated. VERTICAL POSITION Control to position the trace vertically. GAIN ADJ. 1 Screqdriver control to set the basic gain of the dc amplifier. GAIN ADJ. 2 Screwdriver control to set the gain of the ac amplifier to 10. VOLTS/CM Twelve-position switch to select the calibrated vertical-deflection sensitivities. VARIABLE Control to vary the gain over a range of about 2 1/2 to 1. above excerpts from Tektronix Type B Plug-In Instruction Manual OPERATING INSTRUCTIONS Input Connections Two cables can be connected to the preamp at once. You can then select the signal on either cable with the INPUT SELECTOR switch. However, if one signal is very much larger than the other, some crosstalk may occur and the cable having the strong signal should be disconnected. Coupling It is sometimes unnecessary or undesirable to display the dc level of the waveform. In the two AC positions of the INPUT SELECTOR switch, a capacitor in series with the input blocks the dc component of the waveform so that only the ac component is displayed. Deflection Sensitivity The VOLTS/CM switch inserts frequency-compensated attenuators ahead of the amplifier. The VARIABLE control provides continuous adjustment of the deflection sensitivity between the values indicated by the VOLTS/CM switch. NOTEThe VARIABLE control must be clockwise to CALIBRATED position for the sensitivity to be as indicated by the VOLTS/CM control. Gain Adjustment Aging of tubes will affect the gain of the plug-in unit. After the plug-in unit has been in use for a period of time the gain adjustment should be checked. Display a calibrator waveform of 0.2 volts peak to peak with the VOLTS/CM switch in the .05 position. Adjust the GAIN ADJ. 1 control until the displayed waveform is four graticule divisions in amplitude. Be sure the VARIABLE control is turned clockwise to the CALIBRATED position before making this adjustment. Now set the calibrator at 20 MILLIVOLTS and turn the VOLTS/CM switch to .005. Adjust the GAIN ADJ. 2 control until the amplitude of the displayed waveform is four divisions. DC Balance Adjustment The need for adjustment of the DC BAL control is indicated by a shift in the position of the trace as the VARIABLE control is rotated. This is caused by tube aging and the resultant shift in operating potentials. This adjustment should be made after the GAIN ADJ. control is set. Rotate the VARIABLE control back and forth and adjust the DC BAL. control until the trace position is no longer affected by rotation of the VARIABLE control. Positioning Adjustment The VERT POS RANGE control balances the dc output level so the full range of the front-panel control can be utilized. The VERT POS RANGE control is located at the left to the rear of the plug-in unit and is accessible when the left side panel is removed. Center the VERTICAL POSITION control. Adjust the VERT POS RANGE control to cent the trace on the screen. above excerpts from Tektronix Type B Plug-In Instruction Manual MISC PART NUMBERS Knobs 366-042 Knob, Large Black, 1/4" hole part way VARIABLE 366-042 Knob, Large Black, 1/4" hole part way VERTICAL POSITION 366-040 Knob, Large Black, 1/4" hole thru VOLTS/CM 366-038 Knob, Small Red VARIABLE Pots/Switches SW3022 260-081 2 wafer, 4 pos rotary INPUT SELECTOR R3512 311-280 780 ohm Pot VARIABLE R3712 311-028 2 x 100K 2W Pot VERTICAL POSITION SW3142 260-154 6 wafer, 12 pos, rotary VOLTS/CM (serial X3301 up) SW3202 260-080 5 wafer, 11 pos, rotary VOLTS/CM (serial 101-3300X) Tubes V3252 154-040 12AU6 V3302 154-084 6AK5 V3402 154-040 12AU6 V3502 154-028 6BQ7A V3552 154-040 12AU6 V3812 154-039 12AT7 V4002 154-040 12AU6 V4102 154-040/187 12AU6/6DJ8 (6DJ8 for serial # > 3300) V4302 154-084 5654 V4502 154-028/039 6BQ7A/12AT7
