Spot frequencies: Any 10 tones (user settable) within the transmit frequency range
Receiver Characteristics
Characteristics are subject to instrument noise floor (approx –70 dBm). Levels below –70 dBm can be
measured using the PSD Noise test.
Receive frequency:
300 Hz to 2.2 MHz, resolution 1 Hz (optionally to 6 MHz range)
Receive level: - 90 to +24 dBm @ 100 Ω or 135 Ω, resolution 0.1 dB
-90 to +10 dBm @ 600 Ω, resolution 0.1 dB
Level accuracy: -0.5 dB @ 300 Hz @ 0 dBm
±0.2 dB for 1 kHz to 200 kHz @ 0 dBm
±0.5 dB for 200 kHz to 1 MHz @ 0 dBm
±1 dB for 1 MHz to 2.2 MHz @ 0 dBm
±3 dB at 6 MHz @ 0 dBm
Frequency accuracy: ±2 Hz from –40 dBm to +24 dBm
Impedance: 100 Ω, 135 Ω, 600 Ω, bridging (100 kΩ)
Receiver Functions
Single tone:
Numeric display of any tone in the receiver range
Plot: 300 Hz to 4 kHz or 300 Hz to 20 kHz
3-tone slope: 404 Hz, 1004 Hz, and 2804 Hz (ITU: 420 Hz, 1020 Hz and 2820 Hz)
VF Noise Measurement
Range: 0 to -90 dBm subject to instrument noise floor
Accuracy: ±1 dB @ ≥60 dBm
±2 dB @ ≥80 dBm
Filters: None, 3 kHz flat, C-message, C-notched, 50 kbit, 15 kHz flat, D filter (D is
defined by IEEE 743-1995)
