The TekTronix DPO3034 is an impressive oscilloscope with the latest version of Tek’s "digital phosphor" screen and advanced features like extended MATHs functions and waveform replay, zoom and search.
Its bandwidth is 300MHz and the sampling rate is 2.5Gs/s for
each individual channel.
With some 4-channel oscilloscopes, the sampling rate is shared
among the channels or pair of channels. This means that the effective sampling
rate is frequently half that of the quoted specification, when all channels are
However, this oscilloscope achieves 2.5GS/s on each channel at
all times. The vertical resolution of the digitising system is 8 bits and the
sensitivity is better than most comparable oscilloscopes, ranging from 1mV/div
This scope has the latest version of Tek’s so-called "digital
phosphor" display. The colour screen is a 228mm (9-inch) (diagonal) WVGA (wide
VGA: 800 x 480 pixels) LCD that looks bright and shows good contrast.
The display refresh rate is fast at 50kHz.
The screen emulates the desirable features of the phosphors
used in analog oscilloscopes employing CRTs (Cathode Ray Tubes).
The intensity of the traces can be varied over a wide range
while the persistence time can be selected from periods ranging from 10 seconds
down to milliseconds. This is useful when you have fast glitches or you are
using single step triggering.
Interestingly, the display has a wide screen aspect ratio and
is 198mm wide by 120mm high (1.65:1). This allows you to see more time domain
data and effectively gives you the advantage of an even larger screen.
