Amplitude
Characteristics
Low-Pass Filtering: Programmable choice of three configurations:
250 kHz (nominal 3 dB point) 5th-order Bessel
10 MHz (nominal 3 dB point) 7th-order Bessel
No Filter
Output Impedance
(nominal):
50 Ω or 75 Ω (programmable)
Output Disconnect: Uses a relay. Output is unterminated when relay is
open.
DAC Resolution
(including sign):
13 bits (12 bits, sine waves only)
monotonic to 11 bits
DC Volt Function:
Output: into 50 Ω or 75 Ω: -5.12 to +5.11875
volts in nominal
steps of 1.25 mv
into open circuit: -10.24 to +10.2375
volts in nominal
steps of 2.5 mv
Accuracy: (Temperature within 5 °C of
temperature at calibration (Tcal);
module calibrated at 18–28 °C;
output impedance 50 Ω or 75 Ω;
load 50 Ω or 75 Ω respectively, or INF):
0.3% of setting + 0.2% of full-scale
(add for each ° C beyond 5° from Tcal)
0.05% of setting + 0.015% of full-scale
All Built-In Waveforms:
Output Level: into 50 Ω or 75 Ω: 0.32374 to 10.2375 Vpp
into open circuit: 0.64748 to 20.475 Vpp
Output level adjustability is equivalent to 0–30 dB of
attenuation in steps of 0.01 dB.
Sine Waves:
AC Accuracy, 1 kHz, maximum output: ± 0.1 dB
add beyond Tcal ± 5° C: ± 0.005 dB / ° C
Add if output is not at maximum: ± 0.05 dB
Add if frequency is not 1 kHz, flatness error relative to 1 kHz
(specified for 50 Ω or 75 Ω only):
250 kHz filter:
0.1 Hz to 100 kHz: ± 0.05 dB
100 kHz to 250 kHz: ± 0.10 dB
10 MHz filter:
1 kHz to 10.73741824 MHz: ± 0.2 dB
(These flatness values are achieved by active compensation
for filter frequency response in sine wave mode only, and do
not imply dynamic characteristics of arbitrary waveforms.)
