Instruments with Option 15 provide leveled output power over a maximum range of up to 28 dB (up to 123 dB with Option 2).

  • Page 82: Setting Up A Power Level Offset

    Power Leveling Operations Instrument Operation Setting up a Power Level Offset Level offset lets you compensate for a device on the signal generator's output that alters the RF output power level at the point of interest. For example, the power level at the test device may be less or more than the displayed power level because of the loss through an external transmission line or the gain of an amplifier located between the MG3702xA RF output and the test device.
