Step 4. Satisfy Electrical and Environmental
Requirements
NOTE Refer to your network analyzer’s User’s Guide for information on electrical and
environmental requirements for your network analyzer.
1. The line power module on your multiport test set has an autoranging input. It is
designed to be used with an ac power source with a nominal voltage of either
115 V or 230 V.
2. Ensure the available ac power source meets the following requirements:
CAUTION This product has an autoranging line-voltage input. Be sure the supply voltage is
within the specified range.
If the ac line voltage does not fall within these ranges, an autotransformer that
provides third-wire continuity to earth ground should be used.
3. Ensure the operating environment meets the following requirements for safety:
• indoor use
• altitude up to 15,000 feet (4,572 meters)
•temperature 0 °C to 55 °C
• maximum relative humidity 80% for temperatures up to 31 °C decreasing
linearly to 50% relative humidity at 40 °C
• use only in INSTALLATION CATEGORY II, and POLLUTION DEGREE
2, per IEC 1010 and 664 respectively
4. Verify that the power cable is not damaged, and that the power source outlet
provides a protective earth ground contact. Note that the following illustration
depicts only one type of power source outlet. Refer to Figure 4-3 to see the
different types of power cord plugs that can be used with your test set.
