2. Sensitivity 1 ∗ This adjustment
can be performed
only PC test mode.
3. Sensitivity 2 ∗ This adjustment
can be performed
only PC test mode.
*Note:
12dB SINAD or more at -118.5dBm (Mod: 1kHz/±1.5kHz) with preset digit value at each adjustment point.
If less than 12dB SINAD, execute the "Readjustment method 1" procedure at the failed adjustment point.
[Readjustment method 1]
Decrease the digit value to get 12dB SINAD at -118.5dBm (Mod: 1kHz/±1.5kHz).
If it is still NG, execute the "Readjustment method 2" procedure.
[Readjustment method 2]
If the sensitivity is still NG for [Low] or [Low'] point by using method1, conduct the following procedure.
1. Change the data of the failed adjustment point. ([Low] or [Low']) to the following, and store it.
Sens 1 Sens 2
[Low] 54 69
[Low'] 95 108
2. Open Sensitivity 1, and select the failed adjustment point.
3. Set SSG to the following.
SSG Output: -118.5dBm (0.266uV)
4. Decrease the data until the sensitivity becomes 12dB SINAD.
