The Daiwa CN-101L is a cross-needle SWR/Wattmeter covering 1.8 to 150 MHz. The cross-needle movement allows the simultaneous monitoring of forward power, reflected power, and SWR, all without the need of an extra calibration procedure. The meter is switchable for 15, 150 or 1500 watt full scale readings, and has a built-in lamp which can be powered from an external 13.8 VDC source. Supplied with a DC power cord, which is only required for powering the built-in lamp.

Although there is a PEP mode switch,  The CN-101L is NOT well designed for peak power or peak envelope power (PEP) measurement.
