Remote command:
ZVC:Z<m>:I<n>:BANDwidth? on page 1145
Position
Moves the selected signal up or down in the diagram. The visual effect is the same as
for Offset. While the offset sets a current, position is a graphical setting given in divi-
sions. Within a given operation range, modifying the position is equivalent to moving
vertically the display range. The position can only be modified such that the display
range reaches at most the limits of the operation range.
Remote command:
ZVC:Z<m>:I<n>:POSition on page 1147
Skew
Sets the skew, a delay value, that is known from the circuit specifics but cannot be
compensated by the instrument automatically.
Remote command:
ZVC:Z<m>:I<n>:SKEW on page 1150
Shunt mode
Selects the internal or external shunt mode.
Regarding the shunt selection, i.e. the burden voltage level, there is a trade-off
between the burden of the circuit under test and the SNR at the frontend input. The
burden voltage is the DUT circuit loading caused by leads, connectors and the
amperemeter circuit.
From the DUT perspective, the burden voltage has to be kept low not to distort the
device operation. In contrast, from the probe’s view the voltage has to be as large as
possible to obtain a good SNR. For that reason, the external shunt can be applied to
get the best compromise of both for a specific measurement range.
Remote command:
ZVC:Z<m>:I<n>:SHUNt:MODE on page 1148
Internal Shunt Mode
If Shunt mode is set to "Internal shunt", include the settings for the internal shunt
mode.
Max current / shunt ← Internal Shunt Mode
Selects the maximum current and the internal shunt value.
With the maximum current and the internal shunt selection, the operating range of the
amperemeter is specified. At the same time, the burden voltage at the amperemeter
input can be estimated. For values of the total round-trip resistance that can be seen at
the test lead ends, consider the data sheet.
