Making T1 Measurements
The Agilent E7495A/B provide a simple solution for all your T1 testing needs, from
basic transmission testing to BERT testing. For more information about T1 testing,
refer to “Measurement Results” on page 518.
Performing a Basic T1 Analyzer Measurement
Setup Button Selections
• Rx Input: The Primary and Secondary inputs are both affected by this setting.
— Terminate - Sets the input impedance to 100 Ohms. Can be performed only
when the T1 circuit is interrupted (connected into a jack that interrupts the
circuit).
— Monitor - Sets the input impedance to 100 Ohms, inserts 20 dB gain, and
should be selected when connected to a 'Monitor' jack.
— Bridge - Sets the input impedance >1000 Ohms and should be selected when
bridging on to a T1 circuit.
