25 MHz Oscilloscope Touts Auto-scale, FFT and Trigger Hold

Saelig Company, Inc. announced the PDS5022S 25 MHz two-channel benchtop oscilloscope with Auto-scale, FFT, and trigger hold – added features normally found on more expensive instruments. Autoscale can be set to 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 the hands free. FFT allows users to instantly see the frequency spectrum of the signal under test, and Trigger Hold allows users to introduce a delay relative to the trigger point so that a different part of the signal can be seen. The also includes video trigger, auto-measurements, large 8-inch full color LCD display, 100 MS/s sampling, XY Mode, auto- set, averaging, math functions, USB output and waveform storage. PDS5022S can automatically measure and display frequency and peak-peak/rms/mean values, but cursors can also be moved to make individual readings.
