NEW: Deep Memory FFT | Up to 1 Million FFTs
The new Deep Memory FFT feature is now available in 4 steps:
- FFT8k (default)
- FFT32k
- FFT128k
- FFT1M
The Deep Memory FFT feature will offer much smaller RBWs within the same span which will result in a sensitivity boost and can be purchased from today on for all SPECTRAN V6 units.
As an example you get the following noise floor and RBWs vs FFT size (@ -60dBm RefLevel and 2MHz span @ 2,22GHz):
- FFT8k = -146dBm @ 480Hz (smallest possible RBW)
- FFT16k = -152dBm @ 120Hz (smallest possible RBW)
- FFT128k = -158dBm @ 30Hz (smallest possible RBW)
- FFT1M = -167dBm @ 4Hz (smallest possible RBW)

We just improved the Deep Memory FFT by adding and additional much smaller 1/64 and 1/128 RTBW span.
This offers the following improved noise floor and RBWs vs FFT size (@ -60dBm RefLevel, Span 600kHz @ 2,44GHz):
- FFT8k = -151dBm @ 120Hz (smallest possible RBW)
- FFT32k = -157dBm @ 30Hz (smallest possible RBW)
- FFT128k = -163dBm @ 8Hz (smallest possible RBW)
- FFT1M = -172dBm @ 1Hz (smallest possible RBW)

We improved the Deep Memory FFT again by adding and additional much smaller 1/256 and 1/512 RTBW span.
This offers the following improved noise floor and RBWs vs FFT size (@ -60dBm RefLevel, Span 150kHz @ 2,44GHz):
- FFT8k = -156dBm @ 30Hz (smallest possible RBW)
- FFT32k = -162dBm @ 7Hz (smallest possible RBW)
- FFT128k = -168dBm @ 2Hz (smallest possible RBW)
- FFT1M = -177dBm @ 235mHz (smallest possible RBW)
