The Table 12-1 lists the available control signals.
"Global Trigger 1/2"
Input for triggering custom digital modulations, digital standards and
ARB. A trigger event affects the signal generation in all basebands for
which the "Global Trigger" signal is enabled.
"Global Next Segment 1/2"
Input next segment for triggering of multi-segment waveform files
(see Chapter 5.10, "Generating Multi-Segment Waveform Files",
on page 351).
"Baseband <BB> Marker 1/2/3"
Marker signal output for triggering and control of external devices with
user-definable marker signals.
Where <BB> (A/B/C/D or 1/2/3/4) indicates the baseband the signal
is related to.
Available marker signals depend on the system configuration, see
Table 12-1.
"Feedback"
Input for global feedback signal, required for 3GPP HSUPA HARQ
Feedback, 3GPP Dynamic Power Control or EUTRA/LTE Closed
Loop BS tests.
"Pulse In A/B"
Input of external pulse signal or input of external trigger/gate signal
for internal pulse generator (see Chapter 8.8.4.3, "Pulse Generator
Settings", on page 547).
"Pulse Out A/B"
Output of the internal pulse signal generated by the internal pulse
generator (see Chapter 8.8.4.3, "Pulse Generator Settings",
on page 547).
"Signal Valid A/B"
Automatically generated output signal that marks the valid signal
times (valid level and frequency) for all analog modulations.
The signal is indicated by the "T/E/P/V" status LEDs near to the "RF"
block.
(see also Chapter 8.8.4, "Modulation Settings", on page 540).
"Signal Valid A/B Neg"
Inverted version "Signal Valid A/B"; the output signal is low during the
valid signal times.
"Sync A/B"
Output for internal Sync signals for pulse modulation.
Sync signals are generated at the beginning of a list or a sweep and
used for synchronization to other instruments (see also Chapter 8.7,
"Varying the RF Signal in List or Sweep Mode", on page 491).
"Video A/B"
Output of the external or internal pulse modulation signal (video sig-
nal). See also Chapter 8.8.4.1, "Pulse Modulation Settings",
on page 540
