Page: 265 / 283

9.1 Output
EC1000SA 9-5
m) Small amplitude frequency response
(When signal source mode is INT or SYNC only)
AC mode 40 Hz to 550 Hz:
±
1%
AC+DC mode 40 Hz to 550 Hz:
±
1%
(100 V range, output voltage is 20 Vrms, 50 Hz rating)
(When signal source mode is SYNC, the condition of the
frequency is within the synchronization frequency range.)
n) Output voltage distortion factor 0.5% or less
(50 Hz or 60 Hz, 50% or higher of the rated output voltage, the
maximum output current or lower, THD+N)
o) Output voltage stability
Fluctuation with output current: 45 Hz to 65 Hz Within
±
0.15%
DC, 40 Hz to 550 Hz Within
±
0.5%
(In the case that the output current is changed from 0% to 100%
of the maximum output current, at the output terminal, the rated
output voltage)
Fluctuation with input voltage: Within
±
0.2%
(The power supply input voltage is 100 V, 120 V or 230 V, no
load, the rated output voltage)
p) Output DC offset
100 V range: Within
±
50 mV (typ., fine adjustment available)
200 V range: Within
±
100 mV (typ., fine adjustment available)
(AC - INT mode, output voltage setting = 0 V)
