module, and 20° to 35 °C for environment temperature unless otherwise noted
Specifications describe the warranted performance of calibrated instruments. Data represented in this
• Specifications are valid from 45° to 75 °C for individual module temperature, as reported by the
• Calibrated instrument has been stored for a minimum of 2 hours within the allowed operating range
• If instrument has previously been stored at a temperature range inside the allowed storage range,
but outside the allowed operating range, instrument must have been stored for a minimum of 2 hours
within the allowed operating range before turn-on
• 45-minute warm-up time
条件：Typical describes additional product performance information that is not covered by the product warranty.
(approximately 25 °C) after alignment within the stated alignment time and temperature limits.
Nominal values indicate expected performance or describe product performance that is useful in the
application of the product but are not covered by the product warranty.
• The RF, IF, and Source Alignments have been run within the previous
7 days
• An “Align ALL” has been run within the previous
8 hours
• If the temperature has changed more than
5 °C from the previous “Align ALL”
It is performance beyond specifications that 80% of the units exhibit with a
95% confidence level. This
data, shown in italics, does not include measurement uncertainty, and is valid only at room temperature
Recommended best practices
• Use slot blockers and EMC filler panels in empty module slots to ensure proper operating
temperatures. Keysight chassis and slot blockers optimize module temperature performance and
• Set chassis fan to high at environmental temperatures above
45 °C
• Testing radios >
50 watts should be done in a climate-controlled environment to minimize thermal
