5.12 HANDLER MODE

In HANDLER MODE the front panel connections are reconfigured to make the analyzer compatible with many existing 4-terminal fixtures and scanners (see Figure 5-3 for the connection protocol for HANDLER MODE). The screen layout is similar to IMPEDANCE

MODE but with the ability to measure turns ratio. The bar graph analogue scale is not available in HANDLER MODE.

5.12.1 Use of HANDLER MODE

1) Before any measurements are made using HANDLER MODE calibration MUST be carried, see section 4.6—Handler Calibration for information and methods of handler calibration.

2) Rdc and AC measurements are performed in the same way as IMPEDANCE MODE.

See section 4.7—Measuring a Component in IMPEDANCE MODE

3) Turns ratio measurements are performed in the same way as TRANSFORMER MODE.

See section 5.7. Turns ratio measurements in HANDLER MODE are made under 2terminal operation so the effects of measurement lead impedance and transformer shunt impedance cannot be avoided.

5.13 TELECOMS MODE

TELECOMS MODE allows line-matching-transformer insertion loss and return loss to be derived. The user may specify values of source impedance and terminating resistance. A damped network may also be selected with user-specified values and, if required, a DC blocking capacitor in the source line. The pictures below show the three configurations with default component values.
