The Yokogawa DL750P is a two-in-one instrument that combines a fully functional oscilloscope with a high-resolution chart recorder in a single unit. It accepts up to 16 isolated analog input channels plus 16 logic inputs through eight plug-in module slots, and pairs on-screen waveform capture with a built-in A4 thermal printer so that measured signals can be both displayed and recorded directly to paper.
The DL750P is intended for maintenance work in steel plants, power plants, and cogeneration systems; on-board testing for railroads and other vehicles; and heavy machinery development spanning industrial machinery, robotics, and semiconductor manufacturing equipment. It also supports multichannel on-site observation of automobiles and automobile parts, and serves as a replacement for Yokogawa's earlier AR, OR, and LR recording instruments.
ValueTronics stocks and holds its own inventory in a 20,000 square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, where instruments are kept on hand and ready to ship. Every pre-owned unit is inspected and functionally verified in-house before it leaves the building, while new units ship factory-sealed exactly as received from the manufacturer.
The DL750P belongs to Yokogawa's DL750 series, a modular family built around eight plug-in slots that accept up to 16 isolated analog channels plus 16 logic inputs. Rather than a fixed instrument, each unit is assembled from interchangeable modules - high-speed, high-voltage, universal voltage/temperature, strain, acceleration, and frequency types - so the same platform can be tailored to very different measurement tasks.
Within the series, the two main units differ chiefly in their built-in printer. The DL750 carries a 112 mm A6 thermal printer, while the DL750P carries a 210 mm A4 thermal printer with a 200 mm (1600-dot) effective print width, making the DL750P the choice when full-width, high-resolution hard-copy output is the priority.
Each model below links to its own dedicated product page with pre-owned-matched pricing. Select the configuration that fits your channel count, memory, and printer requirements, and review that page for its specific condition and availability.
On the DL750P specifically, the A4 thermal printer records all channels together at 1600-dot vertical resolution and includes a dedicated XY recorder mode that emulates an XY plotter, producing 200 mm x 200 mm high-resolution plots of up to four waveform pairs at once.
Beyond the printer, units in the series scale through memory-expansion suffixes: the standard 2.5 MW per channel (50 MW total) can be raised to 10 MW/CH with /M1, 25 MW/CH with /M2, or 50 MW/CH (1 GW total) with /M3. Optional functions including Ethernet (/C10), an internal 40 GB hard drive (/C8), user-defined math (/G2), the DSP channel function (/G3), and four-output probe power (/P4) further differentiate how a given unit is equipped.
The comparison table that follows summarizes these differences side by side. Because the installed plug-in modules set each channel's sampling rate, resolution, and input type, the achievable performance of any unit depends on its module complement as well as its main-unit and option configuration.
| Model | Type | Channels | Max Sample Rate |
|---|---|---|---|
| DL750P | Main unit (A4 printer) | 16 analog + 16 logic | 10 MS/s |
| DL750 | Main unit (A6 printer) | 16 analog + 16 logic | 10 MS/s |
| 701250 | High-speed isolation | 2 | 10 MS/s |
| 701251 | High-speed isolation | 2 | 1 MS/s |

Important: Universal module (701261/701262) maximum input voltage: 42 V (DC+ACpeak) for satisfying safety standards, 150 V (DC+ACpeak) allowable maximum. Maximum allowable common-mode voltage 42 V (DC+ACpeak), CAT I & CAT II, 30 Vrms.
Important: Plug-in modules are not included with the DL750/DL750P main unit; input modules (701250–701280) must be ordered separately.
Important: Isolated logic measurement leads (758917) require an alligator clip ordered separately; 758917 plus either 758922 or 758929 is required for measurement.
Important: Acquisition memory and voice data backup is maintained by four AA alkaline batteries (approximately 10 hours backup, reference value, with the /M3 option).
Important: Memory expansion options /M1, /M2, and /M3 cannot be specified together (choose only one).
Important: The Zip drive and DC12 V power supply cannot be specified together with the DL750P; the Zip drive (/J2) and DC12 V power (/DC) options are available for the DL750 only.
Important: Before operating the product, read the user's manual thoroughly for proper and safe operation.
Recommended pairing: power Yokogawa current probes 701933 (30 A), 701930 (150 A), or 701931 (500 A) directly from the unit with the /P4 four-output probe-power option.
