The Digital Analysis System (DAS) 9200 Series is a highly modular family of stat-of-the-art digital analysis tools, including a mainframe, a color terminal, acquisition and pattern generation modules, application software packages, and probes. You select the tools and configure them to suit your needs. The result is a custom digital analysis system tailored to your own applications.
You can use the DAS 9200 in two basic ways:
Primarily suited to general-purpose, medium-speed hardware timing analysis. Each 92A16 card provides 16 channels of 4-K deep memory. Working as a single card or as a multiple-card module, the 92A16 offers a maximum clocking rate of 200 MHz.
The P6460 is a 100 MHz data acquisition probe with nine data channels and a clock line.
The 92S16 provides up to 18 channels of vectors and two clock channels. Memory depth is 1 K. The maximum clock rate is 50 MHz.
The 92S32 provides up to 36 channels of vectors and four clock channels. Memory depth is 8 K. The maximum clock rate is 50 MHz.
The 92C02 provides a GPIB port and an interface to the DAS 92E9 Expansion Mainframe.
The 7854 combines the features of a high-performance real-time scope with digital storage and waveform processing capabilities. Offering programmable measurement routines, IEEE-488 interface for mass data and program storage, plus simultaneous display of real-time and stored waveforms makes this a great choice for you scope requirements. The 7854's memory stores up to 40 waveforms and 2000 keystrokes which reduces setup time and human error. Some of the other features included are DC to 400 MHz bandwidth @ 10 mV/div, calibrated sweep rates to 500 pS/div and 128, 256, 512, 1024 points of resolution. This is an excellent choice, utilizes the versatility available from the wide range of 7000-Series plug-ins.
Versatility and dependability in this Tektronix Mainframe; Easy to use and accepts three 7000-Series plug-ins; Bandwidth: DC to 100 MHz; Front-panel calibrator output; Provides CRT readout of parameters.
The TEK 7633 100 MHz multi-mode storage mainframe uses a wide variety of plug-ins including logic analyzers, spectrum analyzers, sampling scopes, and of course, oscilloscopes. This three compartment mainframe has a stored writing rate of 1000 cm/µS with display modes of Store, Nonstore, and Save. Store modes include bi-stable, variable persistence, fast bi-stable, and fast variable persistence.
The 7D11 uses the readout system to display the selected delay count on the CRT. Digital delay time to one second read out in 100-nanosecond increments. Additional analog delay time from zero to 100 nanoseconds selected from a calibrated front-panel dial provides added resolution.
Designed for use in the Tek 7000-Series mainframes, provides DC to 100 MHz bandwidth with vertical sensitivities of 1 mV/div to 5 V/div and 1 M Ohms input impedance. As a comparator the 7A13 will provide an accurate (0.1%) positive or negative internal offsetting voltage of up to ±10 V. Other features include: 20,000: 1 CMRR, 4-digit readout, and 10,000 cm effective screen height.
The 7A26 is a dual-channel wide-bandwidth amplifier. Internal gain and compensation circuits are automatically switched to correspond to the setting of the VOLTS/DIV switch. Channel 2 can be inverted for differential measurements.
Designed for use as an amplifier in the Tek 7000-Series Mainframe. DC to 350 MHz, 5 mV to 1 V/div deflection factors (±2%). 50 Ohms, CH2 invert and identify function.
The 7B87 provides calibrated sweep rates from 5 seconds to 10 nanoseconds and triggering to 400 MHz; gives CRT readout of Delay Time and delta Time measurements. The 7B87 also feature an internally-generated clock and external clock input for sequential single sweep acquisition. The frequency range of the internally generated clock is 20.48 mHz to 20.48 MHz.
The 7B87 calibrated sweeps from 5 s to 10 ns and triggering to 400 MHz. Variable hold off and alphanumeric readout are provided. Also, when operating in the AUTO TRIGGERING MODE, a bright baseline trace is displayed in the absence of a trigger signal.
Vertical scales are calibrated in mp (reflection coefficient 0.001) and mV from 2 to 500 units/div in 8 steps. A tape dial: of 4900 ft, 490 ft, 49 ft (air dielectric); 3200 ft, 320 ft, 32 ft (polyethylene dielectric); and 10, 1, and 0.1 µS (time). Time/division settings of 20 pS to 1 µS in 1-2-5 sequence.
DC to 225 MHz; 10 nS to 105 S with averaging times of X1 to X1000 in decade steps, 10 pS max resolution. 6 nS to 105 S with averaging times of X1 to X1000, 0.1 nS resolution. CH B/Ext. clock range is from 10-7 to 104 S. Manual stop watch range: 0 to 105 S. Totalize, CH B range: 0 to 108 counts.
Here is the easy-to-use TEK 7B53A dual time base plug-in, compatible with TEK 7000-Series mainframes. This time base will trigger to 100 MHz and has normal, intensified delaying, delayed, and mixed sweep modes. Delaying sweep speeds are 50 nS to 5 S/div in 25 steps (calibrated) and at least 2.5 times the calibrated sweep rate, continuously variable between steps (uncalibrated). Other very useful functions are X10 MAG, INT. and EXT. (main & delayed) trigger inputs, single sweep, front-panel Cal and fine/coarse position controls.
Bandwidth is from DC to 1 MHz with calibrated ranges from 10 µV to 10 V/div. Other features include selectable upper and lower -3 dB points, 100,000:1 CMRR, and adjustable DC offset control.

The HP 8656B is a programmable synthesized signal generator that combines performance, quality, and economy, covering the 0.1 to 990 MHz frequency range. Offering ±1 dB level accuracy and 0.1 dB resolution with calibrated output levels over the +13 to -127 dBm range, the HP 8656B provides precise output control. In addition, its modulation capabilities include simultaneous and mixed modulation modes from internal (400 Hz and 1 KHz tones) and external sources. These features create a versatile signal generator, for use in a variety of applications.
The HP 8131A is a 500 MHz pulse generator providing differential output signals from 100 mVpp to 5.00 Vpp with fixed transition times of <= 200 ps. One channel is provided standard.
The 8555A is the microwave RF Section for use with 8552-series IF section and the 140-series display section. Together they comprise a receiver that electronically scans an input signal and provides a visual display in the frequency domain. Input signal amplitude is plotted on the CRT as a function of frequency The amplitude of the CRT is calibrated in absolute units of power (dBm) or voltage (µV/mV) (50 ohm system): accordingly, absolute and relative measurements of both amplitude and frequency can be made.
The analyzer RF and IF sections form a highly sensitive super-heterodyne receiver with spectrum-scanning capabilities over the frequency range of 10 MHz to 40 GHz in 14 frequency bands. The analyzer presents a calibrated CRT display up to 2 GHz wide. Absolute calibration accuracy is maintained from 10 MHz to 18.0 GHz in 10 bands, using internal mixing. The frequency range from 12.4 GHz to 40 GHz is covered in 4 bands through external mixers.
The manual entitled Understanding and Operating the 855A Spectrum Analyzer and 8445B Preselector is a good tutorial for this unit.
The 228 is both a constant voltage and constant current source with front panel and IEEE operation. It has four quadrant operation. This means that the voltage or current sources can operate as a source or a sink in either positive or negative polarities. Full power capability of 100W may be obtained in any quadrant.
