PXIe-5860 VST RF Input Dynamic Range Specifications

RF Input Average Noise Density

Table 19. RF Input Average Noise Density (dBm/Hz)
Center Frequency Reference Level RF Input Average Noise Density
50 MHz to 625 MHz -30 dBm -160
>625 MHz to 5.5 GHz -30 dBm -166
>5.5 GHz to 7.5 GHz -30 dBm -165
>7.5 GHz to 8.5 GHz -30 dBm -164
50 MHz to 625 MHz 0 dBm -130
>625 MHz to 8.5 GHz 0 dBm -138
Conditions: Result is the power spectral density expressed in dBm/Hz. 10 averages computed from the root-mean-square average of the input signal across a 1 MHz span after spurs are removed and normalized to a 1 Hz noise bandwidth. Input terminated with a 50 Ω load.
Note Signal analyzer specifications are often provided as displayed average noise level (DANL). To convert average noise density to DANL, subtract 2.51 dB. DANL is lower because it is computed using the average of the logarithm of measurement samples, not the logarithm of the average of measurement samples as provided.

RF Input Third-Order Intermodulation

Center Frequency Reference Level RF Input Third-Order Intercept Point
50 MHz to 625 MHz -30 dBm -7
>625 MHz to 1 GHz -30 dBm -8
>1 GHz to 2 GHz -30 dBm -9
>2 GHz to 8.5 GHz -30 dBm -8
50 MHz to 625 MHz 0 dBm 23
>625 MHz to 3 GHz 0 dBm 21
>3 GHz to 8.5 GHz 0 dBm 22
50 MHz to 625 MHz 15 dBm 38
>625 MHz to 3 GHz 15 dBm 36
>3 GHz to 8.5 GHz 15 dBm 37
Conditions: measured when receiving two -6 dBr tones offset -5 MHz and +5MHz from the center frequency

Excludes RF harmonic spurs.

Conditions: Measured with 0 dBm reference level, receiving a -6 dBr CW tone at the center frequency. Spur search offset from tone ranges from ±10 kHz to the equalized bandwidth.
