3.1.10 Longitudinal conversion loss (LCL)

LCL measurement (asymmetry attenuation) looks at the balance between the Tip-wire with
respect to Ground (GND) compared to the Ring-wire with respect to Ground. In this mea-
surement, a tone is fed symmetrically to the wires with respect to Ground at 1 MHz. If a dif-
ference can be measured between the two wires, an asymmetry is present.
A voltage check is performed before the measurement in which the
voltage limits given in the table (see page 7) may not be exceeded.
The length of the measuring leads can significantly affect the
measurement, so you should always perform your measurements using
the original accessories.
The measuring ranges, resolutions and accuracies of the LCL measurement are set out in
the chapter Technical data, see page 10.
After selecting the "Menu" softkey, the following settings can be made:
- Remote Kit Command
- Remote Kit
- Information Bell
You can obtain further information on the settings in the ARGUSpedia on the
instrument.
