Pulse External pulse modulation input. This input is TTL and
CMOS compatible. Low logic levels are 0 V and high logic
levels are +1 V. Nominal input impedance is 50 Ω. Input
damage levels are ≤ –0.3 V and ≥ +5.3 V.
Trigger in Accepts TTL and CMOS level signals for triggering
point-to-point in sweep mode. Damage levels are ≤ –0.3 V
and ≥ +5.3 V.
Trigger out Outputs a TTL and CMOS compatible level signal for use
with sweep mode. The signal is high at start of dwell, or
when waiting for point trigger in manual sweep mode; low
when dwell is over or point trigger is received. This output
can also be programmed to indicate when the source is
settled, pulse synchronization, or pulse video. Nominal
output impedance 50 ohms. Input damage levels are
≤ –0.3 V and ≥ +5.3 V.
Reference input Accepts a 10 MHz reference signal used to frequency lock
the internal timebase. Option 1ER adds the capability to
lock to a frequency from 1 MHz to 50 MHz. Nominal input
level -3.5 to +20 dBm, impedance 50 Ω, sine or square
waveform.
10 MHz out Outputs the 10 MHz reference signal used by internal
timebase. Level nominally +3.9 dBm. Nominal output
impedance 50 Ω. Input damage level is +16 dBm.
LO in (Option 012) Accepts a signal from a master signal generator that is
used as the LO for MXG vector in order to configure a
phase coherent system. Nominal input levels between 0 to
+7 dBm. Nominal input impedance 50 Ω.
LO out (Option 012) Outputs a reference signal that can be used in a phase
coherent system. Nominal output levels between 0 to
7 dBm. Nominal output impedance 50 Ω.
Digital bus I/O Reserved for future use.
Aux IO The AUX I/O connector provides additional digital signal
(50 pin SCSI II connector) outputs as follows.
Event 1 - 4 (Pin 1 - 4) This connector outputs programmable
timing signals generated by markers 1 - 4. The marker
signals can also routed internally to control the RF blanking
and ALC hold functions. This output is TTL and 3.3 V CMOS
compatible. Damage levels are > +8 V and < –4 V.
USB 2.0 The USB connector provides remote programming
functions via SCPI.
LAN (100 BaseT) The LAN connector provides the same SCPI remote
programming functionality as the GPIB connector. The LAN
connector is also used to access the internal web server
and FTP server. The LAN supports DHCP, sockets SCPI,
VXI-11 SCPI, connection monitoring, dynamic hostname
services, TCP keep alive. This interface is LXI class C and
B compliant. Trigger response time for the immediate LAN
trigger is 0.5 ms (minimum), 4 ms (maximum), 2 ms typical;
delayed/alarm triger is unknown. Trigger output response
time is 0.5 ms (minimum), 4 ms (maximum), 2 ms typical.
GPIB The GPIB connector provides remote programming
functionality via SCPI.
AM External AM input. Nominal input impedance is 50 Ω.
Damage levels are ±5 V.
FM External FM input. Nominal input impedance is 50 Ω.
Damage levels are ±5 V.
