FEATURES
;
The
Tektronix 7B80 & 7B85
are horizontal time bases recommended for use with 7700, 7800 and 7900 Series Mainframes to provide optimum bandwidth/sweep-speed compatibility.
Reach out to Select-Test.com for further assistance.
(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
Δ
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
Δ
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
Δ
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
Tektronix 7A26
is a dual trace plug-in that offers 5 operating modes, trigger-source selectability, and trace identify.
It has vertical sensitivity of 5mV/div to 5V/div and with appropriate mainframe, DC to 200MHz bandwidth is maintained constant over the entire range.
Reach out to Select-Test.com for further assistance.
Other features include a 20MHz bandwidth limit switch which reduces noise in lower-frequency applications.
The
Tektronix
7A13
vertical plug-in is a DC-coupled differential comparator amplifier. It incorporates a number of features that make it particularly versatile, especially in multitrace combination with other 7000 Series vertical plug-ins. It provides excellent common-mode rejection and medium gain characteristics for medium level applications. In can be used as a differential input preamplifier or conventional preamplifier in addition to its use as a comparator.
Reach out to Select-Test.com for further assistance.
The 7A13 has constant bandwidth over the 1 mV/div to 5 V/div relection factor range. The bandwidth is selectable to FULL or 5 MHz for best displayed noise conditions for low-frequency applications.
As a differential amplifier, the 7A13 provides a balanced (+ and -) input for applications requiring rejection of a common-mode signal. The cmrr is 20000:1 from DC to 100 kHz, derating to 200:1 at 20 MHz. The unit can reject up to 10 V of common-mode signal at a deflection factor setting of 1 mV/div signal, increasing to 100 V rejection potential at 10 mV/div (X10 Vc pulled) and 500 V at 0.1 V/div.
As a comparator amplifier, the 7A13 loses its differential capability, but provides an accurate (0.1%) positive or negative internal offsetting voltage covering the common-mode signal range of the unit. A signal of up to ±10 V may be applied to an input (+ or -) at a deflection factor setting of 1 mV/div and, with an opposing Vc (offset voltage), viewed in 10000 segments of 1 mV. The offset voltage is also available as an output for external monitoring.
