Step 1: Ports and Type
Selects the calibrated analyzer ports, the calibration type and specifies the power
meter connection.
Background information
Refer to
Chapter 4.5.7.2, "Calibration Types"
The layout of the main panel depends on the number of test ports available.
Figure 5-20: SMARTerCal(Manual), Step 1: Ports and Type (>4 ports)
Ports
Selects the test port(s) to be calibrated.
It is possible to select any combination of two or more test ports. If you're only interes-
ted in a single port
p
, perform a two-port SMARTerCal for a port pair including
p
(as
Power Port).
Note:
Calibration and port de-/activation.
The way the analyzer fimware activates/deactivates ports after a successfull calibration
(system error correction or power calibration) has slightly changed:
●
In all FW releases, calibrated ports that were previously disabled, are automatically
enabled as single-ended logical ports.
●
Starting with FW version 2.10, uncalibrated ports were disabled in the related
channel(s). If only one of the physical ports forming a balanced port was calibrated,
the balanced port was dissolved and only the uncalibrated (single-ended) port was
disabled.
In earlier FW versions there was no such port deactivation mechanism.
●
Since FW version 2.40 an uncalibrated port is only disabled if it is not used by a
measurement, i.e. if it is not required by any trace of the related channel.
