Observe maximum input voltage
WARNING. Observe all terminal ratings. To avoid damaging the instrument, observe all rating and markings on the product.
Consult the product manual for further ratings information before making connections to the product.
Do not apply a potential to any terminal, including the common terminal, that exceeds the maximum rating of that terminal.
The maximum input voltage for the ATI (Asynchronous Time-Interleaved) input is ±0.75 V
pk
. This is the maximum voltage before
damage occurs.
The maximum input voltage for the TekConnect inputs is ±1.5 V relative to the termination bias (30 mA maximum) on ≤ 1.2 V full
scale settings and 8 V on >1.2 V full scale settings.
Selecting the proper attenuator
The ATI input has a maximum voltage range of 300 mV
FS
. Use of an attenuator can increase the maximum voltage range.

Connector cleaning
All connectors must be kept clean. Dirt in connectors can damage the connector and any connectors the dirty connector is used
with. Dirt will also likely impair the RF performance. All cables, attenuators, and adapters should be stored with connector covers
to keep dust out.
Before each use do the following:
