How do you measure ACPR?
There are two ways of measuring ACPR. The first way is by finding 10*log of the ratio of the total output power to the power in adjacent channel. The second (and much more popular method) is to find the ratio of the output power in a smaller bandwidth around the center of carrier to the power in the adjacent channel.
What does spectrum analyzers measure?
A spectrum analyzer is a device that measures and displays signal amplitude (strength) as it varies by frequency within its frequency range (spectrum). The frequency appears on the horizontal (X) axis, and the amplitude is displayed on the vertical (Y) axis.
How can I improve my Acpr?
By reducing the bandwidth of the analog IF filter, one can now increase the IF gain by lowering the reference level to improve the ACPR capability.
What is a channel power?
Channel power is when one member of the channel attempts to guide and support members of the other channel. The channel member that assumes this position is known as the channel captain. Channel power occurs in four different ways; economic power, expertise, identification, and legitimate right.
What is spectrum channel power?
Spectrum Channel Power shows you how “loud” the transmissions in the spectrum were during the survey. The power can be originating from either Wi-Fi, or from other devices in the same frequency. Most commonly in production networks, most of the channel power is caused by Wi-Fi.

What is reference level dBm?
For example, on power-up, the reference level is 0 dBm, meaning that the top line on the screen is at 0 dBm and you measure the amplitudes of lines in the spectrum down from that level. For example, if the REF LEVEL is set to +10dBm, a signal peak that reaches the top of the display is +10dBm.
What is measurement bandwidth?
Bandwidth is measured as the amount of data that can be transferred from one point to another within a network in a specific amount of time. Typically, bandwidth is expressed as a bitrate and measured in bits per second (bps).
How is RF harmonics measured?
The most straightforward method for measuring harmonic distortion is to use a continuous wave (CW) tone as an input signal, and measure the output signal with a signal analyzer; see Figure 1. A device under test (DUT) might be an RF amplifier or mixer.
