DIFFERENTIAL IQ OUTPUT
(OPTION 009)
When differential IQ outputs are enabled, the signal generator RF is CW only.
Output impedance:
Can be used with single-ended 50 Ω loads or differential 100 Ω loads.
Delivered bias voltages are halved with single-ended loads.
IQ bias voltages: Independent I and Q channel bias voltages settable within the range ±3 V.
Bias voltage: Resolution: 1.0 mV nominal
Accuracy: ±2% ±4 mV max, ±1% ±2 mV typical
Offset: see IQ bias voltages above
Differential offset voltage: Range: ±300 mV
Resolution: 100 µV nominal
Accuracy: ±2% ±3.3 mV max, ±1% ±0.7 mV typical
Level mode: Variable IQ signal level over 45 dB range
Differential signal balance: Typically 0.15 dB at 10 MHz
IQ channel balance: ±0.2 dB at 1 MHz
IQ level imbalance adjust: ±4 dB nominal, continuously variable
IQ signal amplitude: 22.4 mV to 4 V pk-pk per channel
IQ signal amplitude accuracy: <2% at 20 kHz,typically 1.5%, excludes termination errors
Baseband purity (2 V p-p set
voltage at 1 MHz):
2
nd
harmonic: −70 dBc
3
