Metrix GX1010 Notice De Fonctionnement page 100

SYNC OUT logic levels are nominally 0V and 5V from typically 50Ω. SYNC OUT will
withstand a short-circuit.
Do not apply external voltages to this output.
4.1.7.4. TRIG/SWEEP OUT
The function of this output is automatically determined by the generator operating mode.
Except in sweep and HOP modes the output is that of the internal trigger generator, a fixed
amplitude square-wave whose frequency is set on the TRIG or GATE menus. The rising
edge of the trigger generator initiates trigger, burst, gate, etc.
In sweep mode the output is a 3-level waveform, changing from high (4V) to low (0V) at
start of sweep, with narrow 1V pulses at each marker point.
In HOP mode the output goes low on entry to each waveform step and high after the new
frequency and waveshape of that step have been set.
Output levels are nominally 0V and 4V from 1kΩ. TRIG/SWEEP OUT will withstand a
short-circuit.
Do not apply external voltages to this output.
4.1.7.5. RS-232
9-pin D-connector compatible with ARC (Addressable RS232 Chain) system. The pin
connections are shows below:
Pin 2, 3 and 5 may be used as a conventional RS232 interface with XON/XOFF
handshaking. Pins 7,8 and 9 are additionally used when the instrument is connected to the
ARC interface. Signal grounds are connected to instrument ground. The ARC address is
set from the front panel using the I/F menu.
4.1.7.6. GPIB (IEEE-488)
The GPIB interface is an option. It is not isolated; the GPIB signal grounds are connected
to the instrument ground.
The implemented subsets are:
SH1 AH1 T6 TE0 L4 LE0 SR1 RL1 PP1 DC1 DT1 C0 E2
The GPIB address is set from the front panel using the I/F menu.
