N4010A vector signal generator specifications
The specifications apply to the N4010A with Options 102
or 103 installed. The vector signal generator is used in
WLAN receiver tests described earlier in this document.
N4010A-101 and 107 Bluetooth signal source specifications
are different and are given in the Bluetooth section in this
document.
Frequency range 2.402 to 2.484 GHz;
4.800 to 5.875 GHz (Option 103 only)
Frequency accuracy 1 As frequency reference ±25 Hz 2
Output power range 2.402 to 2.484 GHz: –10 to –95 dBm 1

1. Verified using CW measurements.
2. Example, using the 10 MHz reference with accuracy of 10 Hz (1 ppm),
at frequency of 2.402 GHz, frequency accuracy would be in the range
±((2.402 GHz x 10 Hz)/10 MHz) ±25 Hz = ±2402 Hz ±25Hz = ±2427 Hz.
3. Add 0.013 dB/°C from 30 to 55 °C, add 0.02 dB/°C from 20 to 0 °C.
4. Typical specification applies to instruments serial number GB4617 or
greater, or instruments with the serial number starting MY.
5. Up to 40 MHz bandwidth.
6. Specification applies to instruments serial number GB4617 or greater, or
instruments with the serial number starting MY; otherwise this specifica-
tion is < 10%.
7. Specification applies to instruments with Option 108.
