Chapter 3 — Performance Verification 3-3 Electrostatic Discharge Prevention

3-3 Electrostatic Discharge Prevention
All electronic devices, components, and instruments can be damaged by electrostatic discharge. Thus, it is
important to take preventative measures to protect the instrument from damage caused by electrostatic
discharge.
Prior to connecting a test port cable to the VNA test port, take steps to eliminate the static charges built-up on
the test port cable. This can be done by terminating the open-end of the cable with the short from the
calibration kit and then grounding the outer conductor of the connector on the cable.
3-4 Calibration and Measurement Conditions
Extremes in the surrounding environmental conditions and the condition and stability of the test port
connectors, through-cable, and calibration kit determine system measurement integrity to a large extent.
These are all user controlled conditions, and as such, should be evaluated periodically for impact on system
performance. If these conditions vary significantly with time, the system verification procedures should be
performed more often than the recommended annual cycle.
The standard conditions specified below must be observed when performing any of the operations in this
chapter – both during calibration and during measurement.
• Warm-up Time: 90 minutes
• Temperature: For System Verification, 23 °C ± 3 °C
with < 1 °C variation from calibration temperature
For other tests, 25 °C ± 5 °C
• Relative Humidity: 20 % to 50 % recommended
