Basic Measurement Characteristics
Oscillator level
Output Impedance
*1. It is possible to set more than 0 dBm (447 mV, 8.94 mA) oscillator level at
frequency > 1 GHz. However, the characteristics at this setting are not guaranteed.
*2. When the unit is set at mV or mA, the entered value is rounded to 0.1 dBm resolution.
