Introduction - Berkeley Varitronics Systems YellowFrog 2 Wideband Manual

1. Introduction

The Yellow Frog 2 (YF2) Power Meter measures true RMS power over the frequency range of 150
MHz to 2700 MHz for purely sinusoidal (CW) as well as GSM, CDMA and W-CDMA carrier signals.
The measurable power range is 15dBm to 50dBm. It has a 0.1dB resolution and an accuracy of 0.5dB.
When its output port is terminated by a 50 Ohm impedance, the value of the VSWR observed on its
input port is 1.20 or smaller. It has an LCD display displaying the measured power level in Watts or
dBm, the battery status and three LED indicators. The YF2 can be used either in stand-alone mode or
with a PC (desktop, laptop or notebook) via its USB port, for convenient data output in ASCII format.
The interface software and USB drivers provided with the unit are supported by Windows 7, Vista, XP
or 2000 Operating Systems.
The YF2 package comes with the following items:
1. YF2 Power Meter unit
2. AC charger for Li-Ion battery
3. CD-ROM disc containing PC Software and Driver (not shown)
4. USB cable (not shown)
