Amplifier Research 250S1G2Z5 The Amplifier Research 250S1G2z5 is a self-contained, air-cooled, broadband amplifier designed for applications that require instantaneous bandwidth, high gain, and linearity. It is housed in a stylish cabinet and designed for benchtop use, but can be removed for equipment rack mounting.Features and Specifications of the Amplifier Research 250S1G2z5Amplifier include:

Features:

• Provides a minimum of 250 watts of RF power when used with a sweep generator
• Front panel gain control provides convenience of setting desired output level
• RF input leveling circuit:
• Protects the amplifier from RF input overdrive
• Controls RF input level to the RF amplifier first stage when RF input level is increased above 0 dBm
• RF amplifier stages are protected from over-temperature, due to cooling blockage or fan failure, by removing the DC voltage to them 
• Digital Display on front panel indicates operate status and fault conditions when over-temperature or power supply fault occurs
• Control functions and status indications are available remotely in GPIB/IEEE-488 format, RS-232 hardwire and fiber optic, USB and Ethernet
• Bus interface connector on back panel
• Local/Remote switch on front panel assures positive control of local or remote operation
• Low level of spurious signals and linearity make it ideal for these uses:
• As a driver amplifier in testing wireless and communication components and subsystems
• As a test instrument covering mutiple frequency bands
• For communication technologies including CDMA, W-CDMA, TDMA, GSM, etc.
• EMC Test applications where undistorted modulation envelopes are preferred
