ME1000 RF Circuit Design
Quick Start Guide - 16/23
•
Reconnect the spectrum
analyzer to the IF Out port.
•
Use a jumper cable to connect
the Synthesizer Out port to the
Mixer LO In port.
•
Reconnect the signal generator
(868 MHz, –15 dBm) to the
Mixer RF In port.
•
Check the spectrum analyzer
whether the mixer produces
intermodulation products, such
as (±n818 ± m868) MHz.
Verifying the End-To-End Receiver
•
Reconnect the spectrum
analyzer to the Bandpass Filter
Out port.
•
Reconnect the signal generator
to the Bandpass Filter In port.
Use jumper cables to connect
all the ports shown on the right.
•
Click LNA Off and IF Amplifier
Off to turn on the LNA and IF
Amp.
•
Check the spectrum analyzer
whether the signal generator
output is downconverted from
868 MHz to 50 MHz.
•
Power off the signal generator.
