PSM1700 PsimetriQ user manual

Transformer analyser fixture, TAF02
This fixture is no longer available. However the facility is
still available on the instrument for users who already
have one. Whilst TAF02 can’t be directly selected in the
AUX menu, Config,122,3 can be used to set the fixture
option in the AUX menu to TAF02.
Isolation transformer
When testing the stability of control loops it is necessary to
inject a small disturbance signal into the loop. PsimetriQ
output is ground referenced so it is necessary to isolate
the output before it can be connected to the loop.
The standard isolation transformer provides an isolated
output at a reduced signal level of about 1/6 of the direct
output level over a frequency range of about 10Hz to
200kHz.
Other isolation transformers are available for high
frequency or high voltage applications.
Connections are via BNC connectors – one is grounded to
the case the other is isolated. The grounded connector
should be connected to the OUTPUT connector of PsimetriQ
– the isolated connector should be wired to the circuit
under test.
