Sine Wave Spectral Purity
Output frequencies less than 250 kHz are characterized using the
250 kHz filter, higher output frequencies with the 10 MHz filter.
Frequencies given below refer to the desired output sine wave (fc).
Total Harmonic Distortion (through 9th harmonic):
10 Hz–250 kHz -60 dBc
250 kHz–4 MHz: [-60 + 20 log
10
(fc / 250k)] dBc
4 MHz–10 MHz: -36 dBc
Nonharmonic Spurious and Clock Components (to 150 MHz):
10 Hz–1 MHz: the greater of -60 dBc or -60 dBm
1 MHz–4 MHz: 50 dBc
4 MHz–10 MHz: -45 dBc
Arbitrary Waveforms (includes square, triangle, and ramp waveforms):
DAC Full-Scale:
into 50 Ω or 75 Ω:
into open circuit:
0.16187 to 5.11875 volts
0.32374 to 10.2375 volts
The output voltage corresponding to DAC full-scale can be
adjusted, over the indicated 30 dB range, with resolution
equivalent to steps of 0.01 dB.
DC Accuracy:0.9% of setting.

Step Response (no filter) (typical)
Rise/Fall Time 10–90%:
Precursors/Overshoot:

Slew Rate (no filter) (typical)
into 50 Ω:
into open circuit:
750 V/µs
1470 V/µs
DC Offset:
Resolution:12 bits including sign
Limit (of waveform + offset):
into 50 Ω or 75 Ω:
waveform peak(*) volts ≥ 1.02486:
waveform peak(*) volts < 1.02486:
± 5.5 v
± 1.1 v
into high impedance load:
waveform peak(*) volts ≥ 2.04972:
waveform peak(*) volts < 2.04972:
± 11 v
± 2.2 v
(*): As used in this table, “waveform peak volts”
means the voltage corresponding to DAC full-scale.
Accuracy:1% of setting + 0.2% of limit
Beyond Tcal ± 5° C, add 0.015% of limit per °C.
