Scroll through waveform samples
Staff -- Test & Measurement World, 3/1/2006
Tektronix has produced what can only be described as the high end of the low-end range with the DPO4000 series of oscilloscopes. These scopes differ from other Tektronix models, because of their 10 Msamples of waveform memory per channel and because of a feature called Wave Inspector, which helps you search through the scope's long memory to find the event of interest.
Wave Inspector adds a knob and eight buttons to the scope's front panel. The knob has two parts: pan and zoom. You can mark distinct points on a waveform, and you can use a particular characteristic of a waveform as a trigger.
The DPO4000 series has a 10.4-in. LCD display and is just 5.4-in. deep. Three four-channel models cover 350 MHz, 500 MHz, and 1 GHz, and a two-channel model covers 350 MHz. The scopes also include a USB peripheral port on the front panel and a slot for a CompactFlash drive.
Price: $7000 to $14,000. Tektronix, www.tektronix.com.
