 ===== General Description =====
 The Spectrum Analyzer instrument captures the signal in frequency domain where the signals are displayed as a function of their frequency.
-The M2K’s Spectrum Analyzer makes use of probes 1 and 2 which are capable of measuring signals at ±20V.

   - **Type**: The options available in the drop down menu are the several types of averaging available in Scopy’s Spectrum Analyzer. This will improve the accuracy and repeatability of measurements. The summary of the averaging types are written below.
   - **Window**: Determines the type of FFT computation to be used. \\
-  - **Averaging **: Sets the desired amount of averaging from 1 to 100.\\
+  - **CH Thickness **: Sets the desired thickness for each plot signal.\\
+  - **Gain mode**: Change the gain mode for each channel. Available options are "Low" (-25V to 25V) and "High" (-2.5V to 2.5V). \\
+  - **Snapshot button**: Create a snapshot of the current channel and add it as a reference channel (see screenshot attached below). \\
 Here’s a brief suggestion of the window functions based on the input signal:
