• These additional components cause insertion
losses or gains to the test system.
• Passive device: cables, filters, or switches
• Active device: amplifiers or mixers
• Ensure an accurate amplitude level at the input
to your DUT
• The commonly used method is to use a vector
network analyzer (VNA) to measure the gain or
loss of the entire signal path and enter
correction values into the signal generator.
