Operational Check

Operational Check Procedure (Option 002)

The N5280A operational check can be verified using two Sources with a Power
Meter and Power Sensor.

Requirements for Operational Check

The N5280A operational check measures the signal paths from the LO INPUT
to the LO OUTPUT (LO AUX) and each of the four internal mixers, using a
power divider. Internally, the LO signal is mixed with RF input signals supplied
through each of the RF INPUTS (A, B, C, and D) and measured at each of the IF
OUTPUTS (A, B, C, and D). The following process demonstrates that all
associated switches, connectors, cables and circuitry are operational.

Required Hardware

To demonstrate that the N5280A is operating properly requires external
equipment - the same equipment that would be used to perform a field
calibration of the N5280A in a system. This external equipment includes two
precision signal generators and a power meter with a power sensor and power
sensor cable. The module interconnect cables are not used when performing
this operational check; instead, two high-quality flexible 3.5 mm cables are
needed along with adapters.

Please refer to the following table for recommended equipment.
