Site Preparation
Site preparation includes the environmental and electrical requirements necessary for the 85108
system to operate within its specifications. Make sure your site meets these requirements before
installing the system.
85108L Environmental Requirements
The environmental requirements of the 85108 system are given below. These characteristics are the
same as those for the 8510C network analyzer.
Accuracy-Enhanced Measurement Requirements
Accuracy-enhanced (error corrected) measurements require the ambient temperature of the
pulsed-RF network analyzer system to be maintained within ±1 °C of the ambient temperature at
measurement calibration. The measurement calibration temperature must be within the operating
temperature range of the calibration kit (typically 20 to 26 °C). Refer to the appropriate calibration
kit manual for the actual operating temperature of the calibration kit.
Accuracy Enhanced Temperature = Measurement Calibration Temperature ± 1 °C
Power Requirements
Install the required ac power at all necessary locations. Place air conditioning equipment or other
motor-operated equipment on a different ac line than that used for the system. Refer to Table 2-2 for
a list of the maximum VA power ratings of the Agilent instruments used in the 85108 system.
Three-wire power cables must be used with all instruments. These cables provide the required
ground when connected to an appropriate outlet.
System Heating and Cooling
Install air conditioning and heating if required. Air conditioning requirements depend on the
amount of heat produced by the instruments. Use the BTU/hour ratings from Table 2-2 to
determine the total rating of your system. Each VA rating is multiplied by 3.4 to determine the
BTU/hour rating of each instrument.
Temperature +5 °C to 40 °C (+41°F to 104 °F)
Relative Humidity 5% to 95% at +40 °C or less (non-condensing)
Altitude Up to 4,600 meters (approximately 15,000 feet)
