DAIWA CN-901-HP3 SWR Meter / Wattmeter from 1.8 to 200 Mhz Watts 3000

Daiwa CN-901HP3

The Daiwa CN-901HP3 is a professional analog SWR and wattmeter designed for amateur radio operators and technical stations. It allows for the simultaneous and direct measurement of forward power (the useful power output of the equipment to the antenna, measured in watts), reflected power, and SWR, facilitating the tuning and optimization of antennas or transmission systems. It requires a 12-volt power supply for operation.

It operates across a wide frequency range from approximately 1.8 MHz to 200 MHz and supports power levels up to 3000 W , making it suitable for both amateur radio equipment and powerful stations or technical testing.

It features a crossed needle design that intuitively displays Power, Reflected, and SWR readings on a single instrument, simplifying data interpretation during antenna, tuner, or amplifier testing.

Main differences between CN-901HP3 and CN-901HP : Both models are SWR meters and wattmeters from the CN-901 series and share many basic features: Similar frequency range (approx. 1.8 – 200 MHz).
Cross-needle measurement design for forward and reflected power.
50 O impedance and SO-239 connectors.
SWR and power measurement on multiple HP scales (30/300/2000 W). and HP (30/300/3000 W).
Key differences: PEP (Peak Envelope Power) function: The CN-901HP3 can measure real PEP power in SSB modes, which is particularly useful for measurements.
The HP3 incorporates internal circuit improvements to facilitate direct PEP measurement, making it more versatile for current SSB modes.
CN-901HP good SWR/power meter; suitable for classic HF work.
CN-901HP3 enhanced version with real PEP measurement and expanded capabilities, very useful for modern radio amateurs and stations using modes that require additional precision.
