3) Arm ARB
Press Arm ARB to stop the waveform output manually and wait for the
next trigger.
Note: This menu is valid only when the operation mode after the I/Q
baseband signal is triggered is set to "Arm Auto" or "Arm Retrig".
4) Duration Unit
You can press Dur Unit to set the duration unit of the IQ modulation
wavetable when "Single" trigger is selected.
 SL: trigger by the waveform segment.
 SA: trigger by the data point.
Note: This menu is valid when the operation mode after the I/Q
modulation baseband signal is triggered is "Single".
5) Duration
Press Duration to set the duration of the signal in "Single" trigger.
Note: This menu is only available when the operation mode after the I/Q
modulation baseband signal is triggered is set to "Single". Besides, this
value defines the number of points (
r
N
) within the duration and the
instrument acquires the actual time (
r
T
) according to the current sample
rate (
a
S
). They satisfy the following relation:

r
SN T =
.
6) External Delay
Press Ext Delay to set the delay of the response to the trigger when the
external trigger signal is received.
Note: This menu is only available when the trigger mode of the baseband
output of I/Q modulation is set to "Ext". This value defines the number of
points (
d
N
) and the instrument acquires the actual delay time (
d
T
)
according to the current sample rate (
a
S
). They satisfy the following
relation:

T =
.
7) External Inhibit
Press Ext Inhibit to set the time from when an external trigger signal is
received to when the instrument receives the next trigger signal.
Note: This menu is only available when the trigger mode of the baseband
output of I/Q modulation is set to "Ext". This value defines the number of
points (
i
N
) and the instrument acquires the actual inhibit time (
i
T
)
according to the current sample rate (
a
S
). They satisfy the following
