Operation
8. Increase the span in the Spectrum
display to 500 MHz.
Because Spectrum is the selected
display, the acquisition parameters
adjust automatically to meet the needs
of the display. The 500 MHz span
exceeds the real-time bandwidth of the
instrument. As a result, the instrument
will change to swept mode.
9. Look at the Status bar. The readout
“Swept” indicates when acquisitions are
swept.
When the acquisitions are in “Real Time,”
all measurements usually run. If the
acquisitions are swept, only the selected
display can run.
10. Click the Amplitude vs Time display to
make it the active display.
The acquisition switches back to
real-time because the selected display
requires real-time. The data is now
suitable for the Amplitude vs Time
display but doesn't contain the full range
of frequencies needed by the Spectrum
display.
In this case, the Spectrum is unable to
run.
