Making E1 Measurements
The Agilent E7495A/B provide a simple solution for all your E1 testing needs, from
basic transmission testing to BERT testing. For more information about E1 testing,
refer to “Measurement Results” on page 318.
Steps for Performing a Basic E1 Analyzer Measurement
Setup Button Selections
• Rx Input: The Primary and Secondary inputs are both affected by this setting.
— Terminate - sets the input impedance to 75 Ohms. Can be performed only
when the E1 circuit is interrupted (connected into a jack that interrupts the
circuit).
— Monitor - sets the input impedance to 75 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 an E1 circuit.
