Making Measurements
Example 7: Stimulus-Response Measurements
Figure 2-40 Increase the dynamic measurement range by using RANGE LVL.
If the actual measured signal is beyond the gain-compression limit, or
below the bottom graticule of the display, an error message will appear
in the lower right corner of the display. In the case shown here, the
passband information is adjusted off-screen in order to view the
rejection range with better resolution. Changing the analyzer settings
to raise the passband information above the top of the screen results in
an ERR 903
A>DLMT.
In normalized mode, ERR 904 B>DLMT also may appear if:
• The calibration trace is off-screen, or
• No calibration has been performed after a preset, or
• Trace B is blank.
To clear this error and ensure a calibrated measurement, recalibrate
and perform a store-thru operation.
