NVOY RANSCEIVER EFERENCE
Specification
Measured in accordance with AS/NZS 4770 with unwanted tone
frequencies +30/+58 kHz and –30/–62 kHz relative to the SCF
With a wanted signal of –69 dBm (RF amp off) and –83 dBm (RF amp
on), the unwanted signal must be greater than –7.7 [–4.3] dBm (RF amp
off) and –23 [–17.7] dBm (RF amp on) to reduce the SINAD to 20 dB
Third-order intercept (unaffected by AGC):
+33 [+38] dBm with RF amp off
+17 [+25] dBm with RF amp on
Less than 3 dB variation in output for input variation between 1.0 [0.5] μV
and 100 mV PD (RF amp on)
Fast attack, slow release (selectable release time)
Typical:
2.4 W into 8 Ω, 5% THD
4 W into 4 Ω, 5% THD
4 W into 2 Ω, 5% THD
±10 ppm (nominal)
±50 Hz below 5 MHz, increasing to ±300 Hz at 30 MHz
Clarifier is automatically reset to mid-frequency with channel change
Better than 25 dB IMD with two 100 mV EMF RF inputs
An increase of input level of 40 dB above the sensitivity level increases
the signal to noise ratio to at least 40 dB
