Special Instructions for the T100 Receiver

There are 4 possible cases for configuring the T100 receiver:

• Case 1: Using single sideband, single polarization.
• Case 2: Using both sidebands of a single polarization.
• Case 3: Using both polarizations (but single sideband for each polarization).
• Case 4: Using both polarizations and both sidebands.

Case 1 is used when you just have a single emission line in interest. Case 2 can be used when you have two emission lines separated by ~2 times the IF (5-7GHz) in frequency space. Case 3 can be used when you have a single emission line in interest, and would want to observe this emission line in both polarizations. This allows you to improve the noise by ~sqrt(2) when properly combined at the data reduction stage, and therefore this is preferred over Case 1 when you have a single emission line in interest. Case 4 can be used when you desire maximum frequency coverage (e.g. for wide-band spectral line surveys).

Below are examples and instructions on how to set up the front-end settings in the device table.

Important note: The T100H/V receiver uses different equalizer number for the different sidebands. Make sure your keep track of the correct EQ# for the sideband you use. Click here for a graphical explanation.

The rest (IF, backend settings) are described in the main device table page. Be sure to use the "Check Param" button before you save.
