• Digital Control Panel (DCP):
• Provides both local and remote control of the amplifier
• Uses a graphic liquid Crystal Display:
• Provides operational presentation of forward power and reflected power
• Provides control status
• Provides reports of internal amplifier status
• Uses menu assigned softkeys
• Uses a single rotary knob
• Uses a dedicated on/off switch
• Offers extensive control and status reporting capability
• Special features:
• Gain control
• Internal/external automatic level control (ALC) with front panel control of the ALC threshold
• Pulse input capability
• RF output level protection
• Internal RF detector which provides an output for use in self-testing or operational modes
• All control functions and status indications are available remotely in GPIB/IEEE-488 format, RS-232 hardwire and fiber optic, USB, and Ethernet
• Bus interface connectoron back panel
• Keylock on front panel assures positive control of local or remote operation
• Low spurious signals, linearity, and load tolerance make it ideal for these various uses:
• RF susceptibility testing
• Antenna/component testing
• Communication technology testing
• As a test instrument covering multiple frequency bands
• Suitable for communication technologies including CDMA, W-CDMA, TDMA, GSM, UWB, WiMAX etc.
