Note
The Kenwood SW-2000 is a through-type SWR and power meter designed for use in the 1.8 to 450 MHz frequency range, depending on the coupler used.
The SW-2000 replaced the earlier SW-200 series, upgrading the design to handle higher power.
Features
– Multiple Coupler Support: The display unit can connect to up to three couplers simultaneously, allowing for the observation of multiple transmitters or antenna systems from one location.
– Dual Meter Display: The unit features dual meters that simultaneously measure forward (FWD) and reflected (REF) power, facilitating fast and easy tuning.
– PEP Measurement: It can measure Peak Envelope Power (PEP) for single sideband (SSB) operations using an operational amplifier to detect voice signal peak power.
– High Sensitivity: The companion detectors offer high sensitivity and flat output characteristics, allowing for power measurements without additional calibration or calculation.
– Separated Display and Coupler: The coupler can be mounted on the rear of the display unit or separated, enabling flexible placement of the display unit.
– PEP Mode Indicator: A dedicated indicator lights up when the PEP measuring mode is selected.
Specifications
The SW-2000's parameters vary depending on the coupler used. It is typically sold with one SWC-3 coupler included.
