Ads are not permitted. What is a good price for a nice used one? I'm not familiar with this particular manufacturer or model. The probe is at least as important as the 'scope itself when evaluating the performance and suitability for use.
The spec page lists the probes as optional equipment, so you might check to see if there are any with it. If so, get the manufacturer and model so we can check the specs. But this can be very useful if you connect it to the input of your frequency counter. They you can use the 'scope as a preamp for the counter, and count your local oscillator signal and such things.
I'll post another reply if I find anything significant in it. But don't put too much weight on this.

Page Precautions Line Voltage Selection The instrument must be operated with the correct Line Voltage Selector switch setting and the correct line fuse for the line voltage selected to prevent damage.
The instrument operates from either a 90 to volts or a to volt line voltage source. Before line voltage is applied to the instrument, make sure the Line Voltage Selector switch is set correctly. Page 12 Installation and handling precautions When placing the OSA in service at your workplace, observe the following precautions for best instrument performance and longest service life.
Avoid placing this instrument in an extremely hot or cold place. Page Operating Instructions Function Of Controls This section contains the information needed to operate the OSA and utilize it in a variety of basic and advanced measurement procedures. Included are the identification and function of controls, connectors, and indicators, startup procedures, basic operating routines, and selected measurement procedures.
Page 18 sweep speed by 10 times. Clockwise rotation moves the traces to the right, counterclockwise rotation moves the traces to the left. Page Miscellaneous Features A sweep. This avoids triggering on intermediate trigger points within the repetition cycle of the desired display.
The holdoff time increases with clockwise rotation. NORM is a position at full counterclockwise Rotation that is used for ordinary signals. Page 21 immediately after ward. Also, get in the habit of turning the brightness way down if the scope is left unattended for any period of time. Page Signal Connections Signal Connections There are three methods of connecting an oscilloscope to the signal you with to observe, They are a simple wire lead, coaxial cable, and scope probes.
A simple lead wire may be sufficient when the signal level is high and the source impedance low such as TTL circuitry , but is not often used. Page Signal Trace Operation If you are using plain lead wire, be certain to first connect a ground wire between the OSA Ground connector 39 and the chassis or ground bus of the circuit under observation. The setup for dual- trace operation is identical to that of Single-trace Operation with the following exceptions ; 1.
Page Trigger Options Trigger options Triggering is often the most difficult operation to perform on an oscilloscope because of the many options available and the exacting requirements of certain signals. Trigger Mode Selection. When the NORM trigger mode is selected, the CRT beam is not swept horizontally across the face of the CRT until a sample of the signal being observed, or another signal harmonically related to it, triggers the timebase. Page 29 fast rise and fall times. However, triggering from the jittering trailing edge will cause the entire trace to jitter, making observation difficult.
Yields a trace that has only the trailin-edge jitter of the original signal. If you are ever in doubt, or have an unsatisfactory display, try both slopes to find the best way. Page X-Y Operation X-Y Operation The internal timebase of the OSA are not utilized in X-Y operation ; deflection in both the vertical and horizontal directions is via external signals. Vertical channel I serves as the X-axis horizontal signal processor, so horizontal and vertical axis have identical control facilities.
Page Delayed-Time Base Operation Delayed-time base operation The OSA contains two timebase, arranged so one the A timebase may provide a delay between a trigger event and the beginning of sweep by the second B timebase. This allows any selected portion of a vaveform, or one pulse of a pulse train, to be spread over the entire CRT screen. Page 34 Triggered B Sweep. Page Measurement Applications However, this is but a small sampling of the many applications possible for this oscilloscope.
Page 37 4. This line has additional calibration marks equal to 0. Count the number of division form the graticule line touching the negative signal peaks to the intersection of the positive signal peak with the central vertical graticule line.
Page 39 Instantaneous Voltages. To measure instantaneous voltage, proceed as follows. Page Time Interval Measurements Time Interval Measurements The second major measurement function of the triggered-sweep oscilloscope is the measurement of time interval.
This possible because the calibrated timebase results in each division of the CRT screen representing a known time interval.
