Low-Cost 60MHz Oscilloscope With Deep Memory

Saelig Company, Inc. announces the SDS6062 - a new, two-channel benchtop scope with 10MSa, a record length for each channel, allowing zooming capability for investigating fast, intermittent pulses. This low-cost versatile scope samples at 500MSa/s and is packed with useful features normally only seen on higher-end DSOs, including deep memory, external, video-capable trigger, auto-measurements, auto-scaling, large 8" full color LCD display, XY mode, auto-set, averaging, math functions, USB output, waveform storage, pass/fail output and a 3-year warranty. Even FFT functionality is included for frequency spectrum display. The SDS6062 comes in a sleek, slim case and can even be fitted with an optional battery, ideal for field or isolated operation.

  • Autoscale can automatically adjust the vertical gain, or the horizontal time base, or both together. This is useful for circuit probing -- as the probe is moved from point to point on a circuit board, the display auto-adjusts for best trace presentation.
  • It functions in the same manner as 'AutoSet', but instead of being a one-time function, it's active until turned off, keeping "hands-free."
  • FFT allows instant display the frequency spectrum of the signal under test.

The SDS6062 can automatically measure and display frequency and peak-peak/rms/mean values, but cursors can also be moved to make individual readings. A built-in self-calibration facility improves measurement accuracy. Video monitoring is also possible since you can trigger on NTSC/PAL/SECAM line or field waveforms. SDS6062 features include: manual cursor measurements, up to 19 automatic measurements (including frequency), high-speed screen update, storage for up to 15 waveforms and set-up parameters, convenient USB serial interface with PC software, 400V (DC+AV peak) maximum input, optional rechargeable battery pack and multi-language capabilities.

This lightweight scope is perfect for any engineer's or student's desk. The USB master and slave connections make printing or storing results easy too. With a large 7.8" 640 x 480 color TFT-LCD, this scope is small enough and light enough to carry anywhere, weighing under 4 lbs. Sensitivity range is 2mV/div to 10V/div with maximum display of ±50V.

Another really useful feature is the ability to store up to 15 waveforms for comparison with live inputs. A persistence control is available too which simulates old analog scopes to compare slow-moving waveforms with previous scans. 'A+B' and 'A-B' math capability is included, while the X-Y display feature can be used to reveal phase delays.
