Inputs and Outputs
Front panel connectors
RF output Outputs the RF signal via a precision N type female connector; see output section for
reverse power protection information
I and Q inputs BNC input accepts “in-phase” and “quadrature” input signals for I/Q modulation;
nominal input impedance is 50 Ω, damage levels are 1 Vrms and 5 Vpeak
USB 2 .0 Used with a memory stick for transferring instrument states, licenses and other files
into or out of the instrument; also used with U2000 Series USB average power sensors

Rear panel connectors
Rear panel inputs and outputs are 3 .3 V CMOS, unless indicated otherwise; CMOS inputs will accept 5 V CMOS, 3 V CMOS, or TTL
voltage levels
RF output (Option 1EM)
Outputs the RF signal via a precision N type female connector
I and Q inputs (Option 1EM) Accepts “in-phase” and “quadrature” input signals for I/Q modulation SMB connector,
nominal input impedance is 50 Ω; damage levels are 1 Vrms and 5 Vpeak; Option 1EM
units will come with 2 SMB to BNC adapters
I and Q outputs BNC outputs the analog I/Q modulation signals from the internal baseband generator;
nominal output impedance 50 Ω, DC coupled; damage levels ± 2 V
I bar and Q bar outputs (Option 1EL) BNC outputs the complement of the I and Q signals for differential applications;
Event 1 This connector outputs the programmable timing signal generated by marker 1
The marker signal can also be routed internally to control the RF blanking and ALC hold
functions; this signal is also available on the AUX I/O connector
Damage levels are > +8 V and < –4 V
Pattern trigger Accepts signal to trigger internal pattern generator to start single pattern output, for
use with the internal baseband generators
Accepts CMOS signal with minimum pulse width of 10 ns
Female BNC
Damage levels are > +8 V and < –4 V
BBTRIG 1 Reserved for arbitrary and real-time baseband generators I/O such as Markers or
trigger inputs
BBTRIG 2 Reserved for arbitrary and real-time baseband generators I/O such as Markers or
trigger inputs
Sweep out Generates output voltage, 0 to +10 V when the signal generator is sweeping; this
output can also be programmed to indicate when the source is settled or output pulse
video and is TTL and CMOS compatible in this mode; output impedance < 1 Ω, can
drive 2 kΩ; damage levels are ± 15 V
Ext 1 External AM/FM/PM #1 input; nominal input impedance is 50 Ω/600 Ω/1M Ω,
nominal; damage levels are ± 5 V
Ext 2 External AM/FM/PM #2 input; nominal input impedance is 50 Ω/600 Ω /1M Ω,
nominal; damage levels are ± 5 V
LF OUT 0 to 5 V peak into 50 Ω, –5 V to 5 V offset, nominal
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
