Tektronix TDS3000B Series vs. Agilent DSO5000A Series
Capturing an Intermittent Pulse
Persistence modes are critical for taking measurements on intermittent
events, like this meta-stable pulse.
Side-by-Side Product Comparison
Each channel represented by
different colors.
Intensity scaling is preserved
when stopped.
Offers variable persistence
capability.

Infinite persistence display, stopped.
When does the DSO5000 really show 1M samples?
Selectable record len gth – up to 10K points on all channel s, all the t ime.
Tektronix TDS3000B
Agilent DSO5000A
To get 1M samples:
` Must be in single shot mode.
` Slower than 50µ s/DIV horizontal setting.
` Turn off 2 channels on 4-channel
instrument, or turn off 1 channel on
2-channel instrument.
If long record length is critical, the
Tektronix 4000 Series provides
10M on all channels, all the time.
