General CharacteristicsExternal 1 inputExternal 2 inputGPIBI inputI out and Q out 1This BNC input connector accepts a ±1 V peak signal for AM,FM, pulse, burst, and phase modulation. For all these modulations,±1 V peak produces the indicated deviation or depth.When ac-coupled inputs are selected for AM, FM, or phasemodulation and the peak input voltage differs from 1 V peak bymore than 3%, the hi/lo annunciator light on the display. Theinput impedance is 50 Ω and the damage levels are 5 V rms and10 V peak.If you configure your signal generator with Option 1EM, thisinput is relocated to a female SMB connector on the rearpanel.This BNC input connector accepts a ±1 V peak signal for AM,FM, phase modulation, and pulse modulation. With AM, FM,or phase modulation, ±1 V peak produces the indicated deviationor depth. With pulse modulation, +1 V is on and 0 V is off.When ac-coupled inputs are selected for AM, FM, or phasemodulation, and the peak voltage differs from 1 V peak by morethan 3%, the hi/lo annunciator light on the display. The inputimpedance is 50 Ω and the damage levels are 5 V rms and10 V peak.If you configure your signal generator with Option 1EM, thisinput is relocated to a female SMB connector on the rearpanel.Allows communication with compatible devices. [rear panel]Accepts an I input either for I/Q modulation or for widebandAM. Nominal input impedance 50 or 600 Ω. Damage levels are1 V rms and 10 V peak. [BNC, front panel] [SMB with Option 1EM]The I out and Q out connectors output the analog componentsof I/Q modulation from the internal baseband generator. Thenominal output impedance of these connectors are 50 Ω,DC-coupled. The damage levels are > +3.5 V and < –3.5 V.The output signal levels into a 50 Ω load are as follows:• (O.5 V peak,), corresponds to one unit length of the I/Q vector.• (0.7 V peak ), for peaks for p/4 DQPSK.• (1.6 V p-p) maximum [Options 601, 602, 001, 002 only].These female BNC connectors are provided on signalgenerators with Option 601 or 602. On signal generators withOption 1EM, these inputs are relocated to rear panel SMBconnectors.1. Parentheses denote typical performance.30
General CharacteristicsI and Q outI and Q are used in conjunction with I and Q to provide a balancedbaseband stimulus. Balanced signals are signals presentin two separate conductors that are symmetrical aboutthe common mode offset, and are opposite in polarity [180degrees out of phase].These female BNC connectors are provided only on signalgenerators with Option 601 or 602. If you configure your signalgenerator with Option 1EM, these inputs are relocated torear panel SMB connectors.LF output Outputs the internally-generated LF source. Outputs 0 to 2.5V peak into 50 Ω, or 0 to 5 Vpeak into high impedance. [BNC,front panel] [SMB with Option 1EM]Pattern trigger inputQ inputAccepts CMOS 1 signal to trigger internal pattern or framegenerator to start single pattern output. Minimum pulse width100 ns. The damage levels are –0.5 to +5.5 V.[BNC, rear panel] [SMB with Option 1EM]Accepts a Q input for I/Q modulation. Nominal input impedance50 or 600 ohms, damage levels are 1 V rms and 10 V peak.[BNC, front panel] [SMB with Option 1EM]RF output Nominal output impedance 50 Ω.[type-N female, front panel]Sweep outputSymbol sync inputSymbol sync outputTrigger inputTrigger outputGenerates output voltage, 0 to +10 V when signal generatoris sweeping. Output impedance < 1 Ω, can drive 2000 Ω.[BNC, rear panel] [SMB with Option 1EM]The CMOS 1 compatible symbol sync connector accepts anexternally supplied symbol sync for digital modulation applications.The expected input is a symbol clock signal. It may beused in two modes. When used as a symbol sync in conjunctionwith a data clock, the signal must be high during thefirst data bit of the symbol. The signal must be valid duringthe falling edge of the data clock signal and may be a singlepulse or continuous. When the symbol sync itself is used asthe [symbol] clock, the falling edge is used to clock the datasignal.The maximum clock rate is 50 MHz. The damage levels are–0.5 to +5.5 V. [BNC, front panel]This female BNC connector is provided on signal generatorswith Option 601 or 602. On signal generators with Option1EM, this input is relocated to a rear panel SMB connector.Outputs CMOS 1 symbol clock for symbol synchronization,one data clock period wide. [Auxiliary I/O connector, rearpanel]Accepts CMOS 1 signal for triggering point-to-point in manualsweep mode, or to trigger start of LF sweep. the damage levelsare –0.5 to +5.5 V. [BNC, rear panel]Outputs a TTL signal: high at start of dwell, or when waitingfor point trigger in manual sweep mode; low when dwell isover or point trigger is received, high or low 2 µs pulse atstart of LF sweep. [BNC, rear panel]1. Rear panel inputs and outputs are 3.3 V CMOS, unless indicated otherwise. CMOS inputs will accept5 V CMOS, 3 V CMOS, or TTL voltage levels.31
