Resolution 0.1% of deviation or 1 Hz, whichever is greater, nominal

Deviation accuracy < ± 2% + 20 Hz (1 kHz rate, deviation is N x 50 kHz)

Modulation frequency response

@ 100 KHz rate

1 dB bandwidth DC/5 Hz to 3 MHz, nominal

3 dB bandwidth DC/1 Hz to 7 MHz, nominal

Carrier frequency accuracy < ± 0.2% of set deviation + (N × 1 Hz)

Relative to CW in DCFM < ± 0.06% of set deviation + (N × 1 Hz), typical

Distortion < 0.4% [1 kHz rate, deviation is N x 50 kHz]

FM using external inputs 1 or 2 Sensitivity +1 V peak for indicated deviation, nominal

Input impedance 50 Ω/600 Ω/1 M Ω, nominal

Paths FM path 1 and FM path 2 are summed

internally for composite modulation

ΦM using external inputs 1 or 2 Sensitivity +1 V peak for indicated deviation, nominal

Input impedance 50 Ω or 600 Ω or 1 M Ω, nominal

Paths ΦM path 1 and ΦM path 2 are summed

internally for composite modulation

1. Speciﬁ cation valid for temperature changes of less than ± 5 °C since last DCFM calibration.

2. Typical performance immediately after a DCFM calibration.
