Amplifier parameters
The HP 8753E allows you to measure the transmission and reflection characteristics of many
amplifiers and active devices. You can measure scalar parameters such as gain, gain flatness,
gain compression, reverse isolation, return loss (SWR), and gain drift versus time. Additionally,
you can measure vector parameters such as deviation from linear phase, group delay, complex
impedance and AM-to-PM conversion.
