1.6 Unpacking
Carefully remove the instrument from the case in an ESD-safe environment.
1.7 Important Notes

Use ESD protection at all times when using the instrument.

Review min/max specifications before applying input signals.

Use high quality SMA-connectors on the SMA ports.
Excessive mating of low quality SMA components to 2.92 mm female
receptacles may degrade the 2.92 mm female receptacle.

Leave dust covers on unused connectors.

Situate the instrument away from heat sources, do not block the fan, and do not
block the exhaust vent (minimum of 8 cm/3 inches clearance).

When using multiple remote heads, allow adequate space around heads for
cooling. If heads are stacked then additional cooling, e.g. using a fan, may be
required.

Use 50 Ω terminations on all unused differential ports.

Use a 8 lbf-in (90 N-cm) torque wrench when attaching connectors.
1.8 Measurement Best Practices

When using differential-mode connections, ensure the cables are phase
balanced for best performance.

Differential connectors may be used single-ended if unused outputs are
terminated in 50 Ω.

Use high quality cables and connector savers (or adaptors).

Keep cable lengths short and minimize the number of cable bends.

Use a 8 lb-in (90 N-cm) torque wrench when attaching connectors.
