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 expect 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).
Optimized for
manufacturing
On the path to faster throughput
and greater uptime, the costeffective EXG X-Series signal
generators are optimized for
manufacturing test. With analog
and vector models, the EXG
provides the signals you’ll need
for basic parametric testing
of components and functional
verification of receivers. Get “just
enough” test at the right price with
the EXG.

1. N is a factor used to help define certain specifications within the document.
2. Time from receipt of SCPI command or trigger signal to within 0.1 ppm of final frequency or within 100 Hz, whichever is greater, and amplitude settled
to within 0.2 dB from 20 to 30 °C. When switching into or out of band 6 amplitude settling time is within 0.3 dB. Implies simultaneous frequency and
amplitude switching.
3. 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.
4. Specifications apply when status register updates are off. For export control purposes CW switching speed to within 0.05% of final frequency is
190 μs (measured).

Simultaneous and composite modulation 2
Simultaneous modulation
All modulation types (I/Q, FM, AM, ΦM, and pulse modulation) may be simultaneously enabled except: FM and
phase modulation cannot be combined and two modulation types cannot be simultaneously generated using the
same modulation source; for example, the baseband I/Q generator, AM, and FM can run concurrently and all will
modulate the output RF (this is useful for simulating signal impairments)
Composite modulation
AM, FM, and ΦM each consist of two modulation paths which are summed internally for composite modulation;
modulation can be any combination of internal or external sources

(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.

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).
