The New 60/100 MHz Standards The PM 3050 to PM 3070 series of oscilloscopes set new standards in the 60 to 100 MHz Oscilloscope range. A new standard in convenience and ease of use together with a new price/ performance standard for instruments of this class. The series consists of four models which are all optionally available in rackmount versions for systems use. These are; • PM 3050 60 MHz 2 channel, single time base • PM 3055 60 MHz 2+1 channel, dual time base • PM 3065 100 MHz 2+1 channel, dual time base • PM 3070 100 MHz 2+1 channel, dual time base with clever cursors Each unit represents a significant step forwards in 'scope technology through their use of microcomputer control to both speed up and simplify the task of signal measurements. Standard features in all models include AUTOSET for single push button set up; a large backlit LCD showing all operating parameters: fast up/down rocker keys and cold switching for high reliability. Measurements In Seconds Just press the green AUTOSET button and automatic setting of channel amplitude, time base sweep speed and triggering takes place, for any signal. If only one channel is connected only one channel is displayed but if both channels are being used then both are automatically scaled and displayed. Triggering takes place on the lower frequency channel to give a clear jitter free display. AUTOSET eliminates time consuming manual range finding and adjustment to give fast accurate results at the touch of one button. Clean and Simple Operation. With up/down rocker keys for amplitude and time base speed selection and pushbuttons for display mode and trigger source selection the operation of this series of oscilloscopes is kept clean and simple. Upon each user action the backlit LCD display is immediately updated making at a glance review of the 'scopes current parameter settings possible rather than having to search the complete front panel to determine the operating conditions. The internal microcomputer prevents illegal setups like incorrect main and delayed timebase settings and clearly identifies on the display noncalibrated amplitude settings or grounded inputs. This avoids incorrect measurements, wasted time and frustration. To speed accurate measurements when using the delayed time base, the LCD gives a digital readout of the delay time so making the calculation of MTB sweep speed x delay time vernier redundant. For infrequent 'scope users the MENU key functions as a 'help' key showing the facilities offered by each key on the ’scope and quickly aquainting the user with its operation. High Reliability and Easy Service Behind the push button operation all input signals are switched by hermaticaliy sealed long life reed relays. These keep out damp and dirt from the active signal paths and ensure long life and long term measurement stability. The advanced modular construction of these 'scopes allows complete functional testing of each subassembly before they are built together to form a complete instrument. An extended burn in period lasting 48 hours then follows before another series of extensive tests takes place. This ensures that zero hour defects are almost completely eliminated and results in long term trouble free operation. In the unlikely event that a failure should occur the modular construction enables easy access to the suspect board without major disassembly. Advanced CRT With 16 KV acceleration and advanced electron optics the CRT display has exceptional brilliance combined with a small spot size maR^"- ing it ideal for measurements on high speed or low repetition rate signals. The effective screen area is a full 8x10 cm. An internally etched graticule is provided for accurate and parallax- free measurements. Graticule illumination is standard on all models. Fast Computer Hook Up For systems use this Smart Scope series can be simply controlled by the GPIB/IEEE-488' bus using the PM 8953A interface. This retrofittable Interface enables the ’scopes to be automatically set up for production testing or QA applications. As the PM 8953A IEEE-488 Interface is a separate unit which simply plugs onto the rear of the ’scope it is extremely interesting for fleet owners as it permits automatic IEEE based recalibration of the complete fleet with only one Interface needing to be purchased, so saving time in recalibration, and money as well. Clever Cursors The PM 3070 offers full cursor measurement capabilities in both time and amplitude axes. Control of all cursor functions is by five keys in the bezel of the CRT which also are used to independently control the intensity of the alpha- numerics and the cursor intensity. Accurate measurements of peak-peak values, voltage ratios, rise times, phase relationships and time ratios are possible with direct numerical display on the CRT. A special facility called the ZOOM function enables the signal between the cursors to be expanded to fill the full width of the screen by automatically adjusting the delay time and delay time base speed. This makes it easy to zoom in on a particular point of interest without having to consider how to set up the delay time section. In addition to the measured data both channel and time base status is displayed on screen and user text or messages can also be specified.
