ScopeCorder gets enhanced functionality

29 June 2005 Test & Measurement

Yokogawa has introduced a new version of its DL750 ScopeCorder waveform measuring instrument, the DL750P, which offers enhanced recorder functionality by the use of a built-in A4 thermal printer. Additionally, it released two new universal measuring modules for this family, the 701261 and 701262, which incorporate both voltage and temperature measurement capability. This brings the total number of modules available to 11.

Yokogawa's DL750 ScopeCorder instruments, which combine oscilloscope and chart recorder functions in a single unit, feature up to 16 isolated analog inputs and 16 logic inputs. The oscilloscope function is used to observe waveforms at high speeds, and the chart recorder function is used to observe them over long periods of time.

The A4 printer used in the DL750P records all channels with an effective chart width of 200 mm (1600 dots), allowing it to be used in exactly the same way as a normal chart recorder, with chart speed, chart length and other settings being set from a front-panel menu.

The DL750P also functions as an oscilloscope with a maximum memory up to one-gigaword and has an instantaneous 'GigaZoom' function for viewing multichannel data with high resolution.

The new 701261 and 701262 universal measuring modules each offer two isolated inputs, which can be used for either voltage, with a sampling rate of 100 kSa/s at 16 bits, or temperature, with a sampling rate of 500 Sa/s. The voltage range is 5 mV/div to 20 V/div while the temperature is programmable for all standard thermocouple types. The two modules differ only with the addition of an anti-aliasing filter (with three ranges of 4 kHz, 400 Hz and 40 Hz) on the 701262.

Typical applications include research and development, manufacturing and maintenance of electrical equipment, used by large-scale plants in most industries, electrical power generation; field testing on railway rolling stock, motor vehicles; and the evaluation of electronic components for mechatronic systems.
