Refer to online help for
assistance with DSB
measurements
The Double Side Band measurement requires careful setup to obtain valid results.
Please refer to the manuals for help with this setup
Requested timeslot number
is not present.
The selected timeslot is not on. (Timeslot is referenced to the trigger point)
RF Start freq should be
greater than IF Fixed
freq
The setup frequencies break the rules for a downconverter measurement. The
measurement will still run, but check setup frequencies are correct before
continuing. The RF Start freq should be greater than the IF Fixed freq for a DSB (for
DSB measurements the setup uses LSB values) downconverter swept LO setup.
Use the graph icon on the DUT setup form to clarify the setup required
RF Start freq should be
greater than IF start
freq
The setup frequencies break the rules for a downconverter measurement. The
measurement will still run, but check setup frequencies are correct before
continuing. The RF start freq should be greater than the IF Start freq’s for an LSB
downconverter fixed LO setup. Use the graph icon on the DUT setup form to clarify
the setup required
RF Start freq should be
greater than LO fixed
freq
The setup frequencies break the rules for a downconverter measurement. The
measurement will still run, but check setup frequencies are correct before
continuing. The RF start freq should be greater than the LO fixed freq’s for an USB
downconverter fixed LO setup. Use the graph icon on the DUT setup form to clarify
the setup required
RF Start freq should be
greater than LO Start
freq
The setup frequencies break the rules for a downconverter measurement. The
measurement will still run, but check setup frequencies are correct before
continuing. The RF start freq should be greater than the LO Start freq’s for an USB
downconverter swept LO setup. Use the graph icon on the DUT setup form to
clarify the setup required
RF Stop freq should be
greater than IF Stop freq
The setup frequencies break the rules for a downconverter measurement. The
measurement will still run, but check setup frequencies are correct before
continuing. The RF Stop freq should be greater than the IF Stop freq’s for an USB or
DSB (for DSB measurements the setup uses LSB values) downconverter fixed LO
setup. Use the graph icon on the DUT setup form to clarify the setup required
Scale/Div only applies in
Log Y Scale
Setting the Scale/Division only makes sense when you are using a logarithmic Y
scale
Signal Track is turned
off when Zero Span is
selected
Signal Track is not available when you have selected Zero Span. So if Zero Span is
entered while in Signal Track is On, Signal Track is turned off
Signals deleted The signals in the signal list were successfully deleted
Sweep Points/Span is <
minimum. Results may be
inaccurate.
The sweep point to span ratio is below the minimum required to ensure the bucket
ratio is large enough to test DVB-T masks
Sweep Setup is not
available in Zero Span
Zero span is a display at a single frequency, so there is no “sweeping” to set up
