●
The Aux. Port is provided by the Additional interfaces option R&S FPL1-B5. If the
"Additional Interfaces" plugin-unit is not detected, the "Channel Bits" tab is hidden.
●
Because the "Additional Interfaces" option is not available for the R&S ZNLE, the
"Channel Bits" tab is always hidden on this instrument.
●
If a R&S ZNL is equipped with theSpectrum analyzer function, the VNA Aux. Port
functionality can only be used if the "Additional Interfaces" plugin-unit is set to the
appropriate mode (see Chapter 7.4.6, "Additional interfaces", on page 133).
Channel Bits (Decimal)
Entry of the 8-bit decimal value (0 ... 255) for the selected channel. The channel bits
control eight output signals at the Aux. Port connector. The signals are 3.3 V TTL sig-
nals which can be used to differentiate between up to 256 independent analyzer
states. For an application example, refer to the description of the remote-control com-
mand.
The decimal values have the following effect:
●
0 means that no output signals are enabled at any of the pins 8, 9, 10, 11 and 16,
17, 18, 19.
●
1 enables the output signal at pin 8. The signal is switched on while a measure-
ment sweep is running in the selected channel. All other signals are inactive.
●
2 enables the output signal at pin 9.
●
3 enables the output signals at pins 8 and 9.
●
...
●
255 enables the output signals at all pins. See also "Pin 16 - 19" on page 532.
Remote command:
OUTPut<Ch>:UPORt[:VALue]
Pin 16 - 19
Selects the control mechanism for the signals at pins 16 to 19 of the Aux. Port connec-
tor.
●
"Channel Bits": Signals are controlled by channel bits 4 to 7. No drive port indica-
tion at the Aux. Port connector.
●
"Drive Ports": Signals indicate the active drive ports. The number of active chan-
nel bits is reduced to 4 (pins 8 to 11).
Remote command:
OUTPut:UPORt:ECBits
10.14 Offset Embed softtool
The "Offset Embed" softtool allows you to define a length offset and loss for each test
port. The offset compensates for the known length and loss of (non-dispersive and per-
fectly matched) transmission lines between the calibrated reference plane and the
DUT. It also contains advanced functions for deembedding/embedding the DUT from/
into more general physical/virtual (matching) networks placed between the calibrated
reference plane and the DUT.
