Definitions and Conditions
Specifications represent warranted performance of a calibrated instrument that
has been stored for a minimum of 2 hours within the operating temperature range
of 0 to 55 °C, unless otherwise stated, and after a 45 minute warm-up period. The
specifications include measurement uncertainty. Data represented in this document
are specifications unless otherwise noted.
Typical (typ) describes additional product performance information that is not
covered by the product warranty. It is performance beyond specifications that 80
percent of the units exhibit with a 90 percent confidence level at room temperature
(approximately 25 °C). Typical performance does not include measurement
uncertainty.
Nominal (nom) values indicate the expected mean or average performance, or an
attribute whose performance is by design, such as the 50 ohm connector. This data
is not warranted and is measured at room temperature (approximately 25 °C).
Measured (meas) describes an attribute measured during the design phase for
purposes of communicating expected performance, such as amplitude drift vs. time.
This data is not warranted and is measured at room temperature (approximately
25 °C).

2. With internal channel corrections on, the frequency switching speed is < 1.3 ms, measured for list mode and SCPI mode cached frequency points.
For the initial frequency point in SCPI mode the time is < 3.3 ms, measured. The instrument will automatically cache the most recently used 1024
frequencies. There is no speed degradation for amplitude-only changes.

Repeatability measures the ability of the instrument to return
to a given power setting after a random excursion to any other
frequency and power setting. It should not be confused with
absolute level accuracy.
Relative level accuracy measures the accuracy of a step
change from any power level to any other power level. This is
useful for large changes (such as 5 dB steps).

generator, AM, and FM can run concurrently and all will modulate the output RF (this is useful for
simulating signal impairments)

Digital baseband inputs/outputs (Option 003/004)
Options 003 and 004 activate the rear panel digital I/Q bus and enable connectivity to the N5102A digital signal interface module. In
output mode (003), you can deliver realistic complex-modulated signals such as LTE, GPS, WLAN, custom pulses and many others
directly to your digital devices and subsystems. In the input mode (004), the interface module ports your digital input to the signal
generator's baseband system, providing a quick and easy way of upconverting to calibrated analog I/Q, IF, or RF frequencies. In
both operating modes, the interface module adapts to your device with the logic type, data format, clock features, and signaling you
require.
Data (requires N5102A)
Digital data formatUser-selectable: 2's complement or binary offset, IQ (I, I-bar, Q, Q-bar) or digital IF output

1. ACPR specifications apply when the instrument is maintained within ± 20 to 30 °C.
2. This is rms power. Convert from rms to peak envelope power (PEP) with the following equation: PEP = rms power + crest factor
(for example, 3GPP test model 1 with 64 DPCH has a crest factor 11.5 dB, therefore at +5 dBm rms, the PEP = 5 dBm + 11.5dB = +16.5 dBm PEP).

1. ACPR specifications apply when the instrument is maintained within ± 20 to 30 °C.
2. This is rms power. Convert from rms to peak envelope power with the following equation: PEP = rms power + crest factor
(for example, 3GPP test model 1 with 64 DPCH has a crest factor 11.5 dB, therefore at +5 dBm rms, the PEP = 5 dBm + 11.5 dB = +16.5 dBm PEP).

Humidity
Relative humidity - type tested at 95%, +40 °C (non-condensing)
Environmental stress
Samples of this product have been type tested in accordance with the Agilent Environmental Test Manual and verified to be robust
against the environmental stresses of storage, transportation and end-use; those stresses include but are not limited to temperature,
humidity, shock, vibration, altitude, and power line conditions; test methods are aligned with IEC 60068-2 and levels are similar to MILPRF-28800F Class 3
Safety
Complies with European Low Voltage Directive 2006/95/EC
Note: Read/write speeds to external memory card will be slower compared to internal solid-state drive (Option 009)
Self-test
Internal diagnostic routines test most modules in a preset condition; for each module, if its node voltages are within acceptable limits,
the module passes the test

Inputs and Outputs
Front panel connectors
RF outputOutputs the RF signal via a precision N type female connector; see output section for
reverse power protection information
I and Q inputsBNC 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 2.0Used 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
For a current list of supported memory sticks, visit
click on Technical Support, and refer to FAQs: Waveform Downloads and Storage
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 outputsBNC 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 1This 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 triggerAccepts 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 1Reserved for arbitrary and real-time baseband generators I/O such as Markers or
trigger inputs
BBTRIG 2Reserved for arbitrary and real-time baseband generators I/O such as Markers or
trigger inputs
Sweep outGenerates 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
Trigger response time for the immediate LAN trigger is 0.5 ms (minimum),
