Calibrating A Transmission (S21) Measurement - Omicron Lab Bode 100 User Manual

7. The calibration icon now shows a green background fill.
This means calibration is activated.
8. You can now connect your DUT and perform a calibrated measurement.

8.2.1 Calibrating a Transmission (S21) measurement

This section shows how to calibrate a Gain, Transmission or S21 measurement performed in the
Transmission / Reflection measurement mode.
The Transmission / Reflection mode offers the possibility to measure Transmission and
Reflection sequentially.
Note: The gain or Thru calibration is only applied to the gain measurement. If you want to
calibrate the Impedance, Reflection or Admittance measurement, refer to
Reflection or One-Port measurement
In the Transmission / Reflection measurement mode Channel 1 is not in use by default. Receiver 1 is
connected internally to the signal source through the internal reference. The Channel 2 termination is
set to 50 Ω, therefore by default the Gain result equals the transmission S-parameter S21 from the
OUTPUT port to the CH2 port. If you choose to measure with the External reference connection,
please refer to 8.2.2 Calibrating a Gain/Phase measurement
