Lab #5: Using Segmented Memory Acquisition Mode
All oscilloscopes have a limited amount of acquisition memory. The amount of
acquisition memory that your scope has will determine the length of time it can
capture while still using a fast sampling rate. You can always capture a long time
span by simply setting the timebase to a long time/div setting. But the scope may
automatically reduce its sample rate in order to capture the long time-span which
will reduce acquired waveform detail and measurement resolution. Using this
scope’s Segmented Memory acquisition mode is another solution to optimize
memory depth and sample rate; especially when attempting to capture multiple
low duty cycle type signals. Keysight 4000 X-Series Oscilloscopes come with
segmented memory as a standard option. Let’s now attempt to capture and
display a simulated low duty cycle radar burst.
1
Connect the channel-1 probe to the Demo 1 terminal and ground.
2
Press
[Default Setup]
on the scope’s front panel.
3
Press
[Help]
; then press the
Training Signals
softkey.
4
Select the
RF Burst
signal.
5
Set channel-1’s V/div setting to
500.0 mV/div
.
6
Set the scope’s timebase to
200.00 ns/div
.
7
Set the scope’s trigger level to approximately
+900 mV
(~2.0 divisions above
center-screen).
8
Press the
[Intensity]
button (under the Entry knob); then set the waveform trace
intensity to
100%
using the Entry knob.
