Sweep Frequency
Defines the sweep range of the Delta-L channel. The entered "Minimum" and "Maxi-
mum" values are set as
when the Delta-L settings are applied
using "OK". Furthermore, the VNA collects data for the LPI computation a the "Mini-
mum" and "Maximum" frequencies (in addition to the other specified
The default "Minimum" is the standard Delta-L start frequency of 10
MHz. The default
"Maximum" is either 20 GHz or the instrument's maximum frequency, whichever is
smaller. Buttons are available to set "Maximum" to the standard Delta-L stop frequen-
cies of 20
GHz and 40
GHz (if within the instrument's frequency range), and to the
instrument's maximum frequency.
If you set the "Minimum" or "Maximum" to a non-standard value, a popup indicates that
the Delta-L measurement possibly does not provide accurate results.

CALCulate:FMODel:DELT:SWEep:FREQuency:MAXimum
Trace
, the VNA deletes the existing traces and sets up the traces whose measure-
ment is required for the selected Delta-L
.
If
"Use Recommended Trace Configuration"
is checked, then each of the new
traces is displayed in a separate diagram. Otherwise, the VNA places all traces in a
single diagram.
If the
option R&S
ZNB/ZNBT-K2 is installed,
"Show TDR Impe-
dances"
adds the TDR-based converted impedance traces to the recommended trace
configuration.

Delta-L measurement
When the Delta-L measurement starts, the analyzer firmware prepares the Delta-L
measurement channel, populates the diagram area with the required measurement
traces, and opens the

Delta-L Measurement dock widget
The "Delta-L Measurement" dock widget is where coupon measurements are per-
formed and/or corresponding touchstone files are selected.
setting in the "Delta-L Settings" dialog determines whether single-
ended or balanced can be measured. "No ports available!" in the dock widget and "No
Trace" in the diagram area indicates that no ports of the selected type are configured.
