Tektronix 7834 w/7A18,7A26,7B80,7D13 dmm plug-in.
Tektronix 7834 Storage Scope - powered up and displays a trace with the 7A26 & 7A18 Vertical Plug-in's.The 7D13 DMM displays the correct voltage of 16.3 VDC on the screen also.
"Designed for fast-writing speed storage applications. 3 Display modes: Nonstore, store, save....and 4-storage modes: Bistable, Variable Resistance, Fast Bistable, Fast Variable Resistance. Power Supply Operates from 115 or 230 Volt nominal supply source (50 to 400 hertz) Verticle bandwidth (400MHz).
Tektronix model 7834 Storage Oscilloscope has a stored writing speed of 2500 cm/ S, enabling storage of single-shot risetimes to 1.4 nS, 3.6 cm high, at eight-divisions amplitude, reduced scan mode. The bandwidth of this mainframe is 400 MHz. This instrument has four storage modes: Bistable, Variable Persistence, Fast Bistable and Fast Variable Persisitence.
* Bistable provides stored displays with long (30 minute) view time.
* Variable persistence gives high contrast displays of both single-shot and repetitive phenomena.
* Fast Bistable increases bistable writing rates to 350 cm/ S (reduced scan).
* Fast Variable Persistence provides the maximum stored writing rate of 2500 cm/ S (reduced scan). View time is at least 30 seconds
The 7A18 Dual-Trace Plug-In Amplifier is the basic building block of 3-trace and 4-trace operation. The unit features constant bandwidth for all deflection factors, 5 operating modes (Ch1, Ch2, ALT, CHOP, ADD), trigger source selectivity and color-keyed control grouping. Features include: Bandwidth: DC to 75MHz; Trace Identify Function; Polarity of Channel 2 is selectable; Deflection Factor: 5 mV/div to 5 V/div; Input R and C: 1 Mohm within 2%; approx. 20 pF
The 7A26 200MHz Amplifier Plug-In is a dual trace plug-in which offers 5 operating modes, trigger-source selectability, and trace identify. Vertical sensitivity of 5 mV/div to 5 V/div and with appropriate mainframe, DC to 200MHz bandwidth over the entire range. Also include a 20MHz bandwidth limit switch which reduces noise in lower-frequency applications.
The 7a26 , a dual trace pluggin amplifier, is the basic building block for three or four trace operation . It features constant bandwidth for all deflection factors. It has 5 operating modes : CH1, CH2, ALT, CHOP, ADD) trigger source selection (Ch1, CH2, Mode.)
Bandwidth may be set at full or limited to 20Mhz.
The 7B80 and 7B85 are horizontal time bases recommended for use with 7700, 7800 and 7900 Series Mainframes to provide optimum bandwidth/sweep-speed compatibility. (Each may be used in any slower 7000 Series Mainframe with some reduction in sweep accruacy at the fastest sweep speed.)
Either plug-in can be used separately as an independent single time base, or they can be combined in any mainframe with two horizontal compartments for delaying and delayed operation.
X-Y displays are available using a 7B80 with Option 02. A front-panel button (DISPLAY MODE) selects either normal sweep or X-Y display. Both signals are applied to vertical (Y) amplifiers, and the desired horizontal (X) signal is then routed through plug-in and mainframe trigger paths to the 7B80. An X-Y mode selection then applies the signal to the horizontal deflection system.
The 7B80 and 7B85 pair provide the time measurement capability in addition to the standard delay time capability. Either time interval is digitally displayed on the crt. A single intensified zone, which you can position anywhere on the trace, identifies the delay time interval (the time from the "A" or main sweep to the start of the intensified zone). Two intensified zones, which you can position anywhere on a trace, identify the time interval (time between intensified zones_. Alternate sweep switching makes it possible to display the information between the intensified zones full screen at the "B" sweep speed. By overlapping the two expanded waveforms, you are confident of the exact positioning of the intensified zones on the "A" sweep. This results in easy-to-make, precise and repeatable timing measurements.
By rotating the TRACE SEPARATION control out of the OFF position, the time mode is activated. Two intensified zones can be independently positioned. As in the conventional delay mode, the DELAY TIME knob adjusts the time to the first intensified zone.
The 7D13A Digital Multimeter Plug-In is designed for use in all 7000-Series Oscilloscope mainframes except those without CRT READOUT. The unit will function in any plug-in compartment. In addition to measuring DC volts, DC current and resistance, temperature measuring capability is also featured in the 7D13A, provided by a temperature sensor on the tip of the voltage / temperature probe (not included). 3 1/2 digit CRT Readout, DC Volts Measurement: 0 to 500 VDC (4 ranges), (0.1% of reading + 1 count), DC Current Measurement: 0 to 2A (4 ranges), Resistance Measurement: 0 to 2 Mohms (5 ranges), Temperature Measurement: -62 to +200 C.
500 V Maximum Common-Mode Voltage
Resistance Ranges: 200, 2K, 20K, 200K, 2M ohms
DC Voltage Ranges: 2, 20, 200, 1000 Volts
