Getting Started
Your First 15 Minutes with the E7495A/B
Spend 15 minutes getting acquainted with the test set:
• “Get to Know the Layout of the E7495A/B” on page 34
• “Install a Battery” on page 37
• “Practice Using the Three-way Power Button” on page 37
• “Make Your First Measurement (Two Port Insertion Loss)” on page 38
Your E7495A/B analyzer is fitted with a transflective screen, which is viewable
under all lighting conditions. If you are using your E7495A/B analyzer in bright
lighting conditions, for example, in direct sunlight, avoid the temptation to shield
the display from the sunlight. In bright lighting conditions, the display is brighter
and easier to read when you allow the light to fall directly on the screen.
CAUTION The display screen should be cleaned with an Isopropyl Alcohol based cleaner and a
soft lint-free cotton cloth. The E7495A/B display has a polycarbonate cover with an
anti-reflective coating, which can be damaged if not cleaned properly. The
anti-reflective coating is a surface treatment and can be scratched if wiped with an
abrasive material. Use only soft lint-free cotton cloth and Isopropyl Alcohol to clean
the display.
When selecting a cleaner make sure it does not contain any Ammonia.
CAUTION The maximum power for the RF In (Port 1) and RF Out/SWR (Port 2) ports is
+20 dBm (100 mW). When using the 8481A/8482A or N8481A/N8482A with
Option CFT Power Sensors, the maximum input power applied to the Power Sensor
is +24 dBm (300 mW). When using the 8481D Power Sensor, the maximum input
power is +20 dBm (100 mW). When directly coupled to a base station (BTS) or
Access Network (AN), the test set can be damaged by excessive power applied to
any of these three ports.
To prevent damage in most situations when you directly couple the test set to a base
station, use the high power attenuator between the test set and the BTS.
