Inputs
Ext Trig
Frequency range: dc to 1 MHz.
Signal range: Threshold nominally TTL level; maximum input ±10 V.
Minimum pulse width: 50 ns for trigger, gate and FSK modes;
1 ms for sweep and hop modes.
Input impedance: 10 k Ω
VCA In
Frequency range: DC - 100 kHz.
Signal range: 2
.
5 V for 100% level change at maximum output.
Input impedance: typically 6 k Ω .
Phase locking
The signals from these sockets are used to phase lock two or more generators.
Clock In/Out
TTL/CMOS threshold level as an input.
Output logic levels nominally 1 V and 4 V from typically 50 Ω as an output.
Sync Out
TTL/CMOS logic levels from typically 50 Ω .
Interfaces
Full remote control facilities are available through the RS232 or GPIB interfaces.
RS232: Variable Baud rate, 9600 Baud maximum. 9-pin D-
connector.
As well as operating in a conventional RS232 mode the
interface can be operated in addressable mode whereby up to
32 instruments can be addressed from one RS232 port.
GPIB (IEEE-488): Conforms with IEEE488.1 and IEEE488.2
General
Display: 20 character x 4 row alphanumeric LCD.
Data Entry: Keyboard selection of mode, waveform etc.
Value entry direct by numeric keys or by rotary control.
Stored Settings: Up to 9 complete instrument set-ups may be stored and
recalled from battery-backed memory.
Size: 3U (130mm) high;
half-rack (212mm) wide;
330mm deep.
Weight: 4.1 kg (9 lb)
Power: 100 V ac, 110-120 V ac or 220-240 V ac ±10 %,
50/60 Hz, adjustable internally;
40 VA max.
Installation category II.
Temperature range: operating: +5 to 40 °C, 20-80 % RH.
storage: -20 to +60 °C
Environmental: Indoor use at altitudes up to 2000 m,
