Allows even more internal settings to be changed.

  • AGC enables/disables the build in Automatic Gain Control. The AGC helps extending the dynamic range of the tinySA but is sometimes causing artifacts. Disabling the AGC can help discovering these artifacts. Disabling of the AGC is recommended when measuring below 1.5MHz or when trying to observe AM modulation. This setting only has impact when attenuation is on manual. See the example of measuring Low Frequencies
  • LNA enables/disables the build in Low Noise Amplifier. Should not be enabled when AGC is enabled. Enabling the LNA can cause severe signal distortion with signals above -20dBm. Switching on the LNA is recommended when measuring low level signals below 1.5MHz. This setting only has impact when attenuation is on manual.
  • BPF enables measurement of the performance of the internal Band Pass Filter. Make sure you connect low and high input connectors with a short SMA cable. This measurement is only available in low input mode. The top of the BPF should be at close to -25dBm and have a flat passband of about 1MHz wide. The stop band of the BPF should be below -80dBm
  • BELOW IF switches the LO to below the IF when measuring below 190MHz. Can be used to detect spurs or mirror signals but may also cause performance degradation. This is normally in automatic mode.
  • DECAY sets the decay speed of the quasi peak measurement
  • ATTACK sets the attack speed of the quasi peak measurement
