You may configure the arbitrary file using the format as
shown in the example below. The file is saved in the *.arb
format.
#Vpeak: 2
#DC offset: 0
#Points:
0
–0.2
–0.4

The following table shows the allowable range of values for
each arbitrary file parameter.
The sampling rate for the arbitrary waveform is fixed at
312.5 kHz. Thus, the interval between samples is 3.2 s
1/312.5).
Parameter Range
Vpeak • 0 to 22.6 Vp (Balanced output
connection)
• 0 to 11.3 Vp (Unbalanced or Common
output connection)
DC offset –11.3 V to 11.3 V
Points 32 to 32768 points
When the DC offset and amplitude are added together, it must not exceed
the maximum voltage for the current output connection type:
• For the Balanced output connection, Vpeak + |DC offset| must be
within 0 V and 22.6 V.
• For the Unbalanced and Common mode output connections,
Vpeak + |DC offset| must be within 0 V and 11.3 V.
