Picotest J2140A Features

• Integrated unit includes 40dB, 20dB and 10dB
• Cascade for greater attenuation
• Improve noise floor or assure small signal measurement

Introduction

There are two common uses for attenuators when used in conjunction with the network analyzer. One is to attenuate the oscillator source signal. While this may seem odd, one of the most common errors in analyzer measurements is using a source signal that is too large. Even though the analyzer allows setting of the signal output amplitude, the lowest setting is often too high to allow an accurate small-signal measurement to be made. The correct amplitude is the smallest amplitude that exceeds the noise floor.
