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.
(Refer to Chapter 7 - ‘Test Conditions’, which lists recommended test
conditions).
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. See 7.3
Explanation of Integration.
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.
Note: The Measure button may be used here as outlined in section 14.5.9.
6. Select OK. The test specification will then be displayed in the program
window.
