4.17. ILOS – INSERTION LOSS
The Insertion loss test measures the output power delivered by a transformer to a
load, relative to the maximum power theoretically available. A voltage is applied to
the input winding and the input/output voltages are measured to calculate the loss.
This test is suitable for audio & telecommunication transformers and checks the
effective losses in the transformer when used for its application.
On selecting "ILOS Insertion Loss" from the available tests window, a dialogue box
will be displayed.
To program the test:
1. Enter the voltage and frequency parameters of the test signal.
(If in doubt, refer to Chapter 7 - ‘Test Conditions’, which lists recommended
test conditions.)
Note also that the Measure button may be used here as outlined in section 3.9.
2. Select the integration time you require.
'Medium' is the default setting. 'Long' will give more stable readings (for
tighter limits) at the expense of an increased test time, and 'Short' will test at the
maximum speed, but may give a slightly noisier reading.
3. Enter the names of the Hi and Lo input terminals and value of source resistance.
4. Enter the names of the Hi and Lo output terminals and value of load resistance.
5. Set the insertion loss limits.
+/- Enter a nominal value and then the limits as negative and positive
values.
>< Enter minimum and maximum values.
> Enter just a minimum value.
6. Select OK. The test specification will then be displayed in the program window.
