Analyses include adjacent channel power ratio (ACPR), error vector magnitude (EVM), noise power ratio (NPR), third-order intermod
ulation (3IM), BER and many others.
Load pull measurements of power, gain, intermod
, intercept, efficiency, AM/PM conversion and adjacent channel power (ACP) are supported.
Today's electronic industry needs a variety of mixers with different electrical characteristics, including DC coupled (capable of operating at |is greater than or equal to~0 Hz) intermediate frequency (IF) port; high dynamic range (better third-order intermod
products); higher 1 dB compression point (normally 3 to 4 dB, lower than the local oscillator (LO) level); higher isolations, LO to RF, LO to IF and RF to IF; and low DC offset.
0.1 to 3.5 GHz high dynamic range amplifiers with unconditional stability, high reverse isolation, excellent SWR, intermod
performance and noise figure; and hybrid microelectronic, surface mount and coaxial packaging for military and commercial product applications.
Setup for Automatic Power Gain and Intermod
If the intermods
levels do not change, then the intermods
created by the spectrum analyzer are not affecting the measurement.
