UXG Agile Signal Generator
10 MHz to 20 or 40 GHz
Definitions and Conditions
Specification (spec): represents 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 1 hour 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. It is performance beyond

specifications that 80% of the units exhibit with a 95% confidence level at room temperature
(approximately 25 °C). Typical performance does not include measurement uncertainty.

Nominal (nom): describes the expected mean or average performance, or an attribute whose
performance is by design, such as the 50 Ω 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).

All of the above apply when using the instrument in its default settings unless otherwise stated.

This data sheet provides a summary of the key performance parameters for UXG signal
generators. All options referenced in this data sheet are described in the UXG configuration
guide (5992-0093EN).

Unless otherwise noted, this data sheet applies to units with serial numbers ending with
5646xxxx or greater.

Leveling modes
ALC on Internal power leveling

ALC off with power alignment Power alignment is a routine that improves level accuracy with ALC off. It aligns the power level with ALC
off to match the power level with ALC on at a customer specified power level. It should be run at regular
intervals and whenever the operating temperature changes ± 5 °C from the alignment temperature.
RF Gating
Turns RF power on/off with external trigger

1.  For EW simulations using option AT2 agile power capability, it is strongly recommended to operate with ALC mode off after running power alignment. If ALC
mode is left on, switching speed performance will be significantly reduced.

1.  Specifications shown represent uncorrected performance at the RF output port. Level accuracy at the DUT input can be significantly improved by running
the UXG user amplitude correction routine with a power sensor.
2.  Specifications apply after running power alignment at +4 dBm power level. It is strongly recommended that EW simulations be performed with ALC mode
off after running power alignment. If ALC mode is left on, switching speed performance will be significantly reduced.
3.  T he Power Alignment routine aligns ALC off level accuracy performance to ALC ON performance at a customer specified power. It should be run at regular
intervals, and whenever the operating temperature changes ± 5 °C from the alignment temperature. For optimal performance in applications where the
instrument will be used at more than one power level, execute power alignment at a power level < 5 dBm and with the output attenuation set to the desired
operating condition.
4.  For frequencies > 17 to 20 GHz, level accuracy degrades by an additional 0.5 dB.

User corrections
The User Corrections capability can apply corrections across frequency for amplitude, phase and time. Corrections can only be applied when the UXG
operates in Streaming Mode. Amplitude-only corrections can be done with a power sensor. In order to maximize agile dynamic range, it may necessary to
modify mechanical attenuator settings depending on PDW amplitude values and the peak amplitude loss being corrected.

Synchronization
Multiple UXG units can be synchronized together to have phase coherent outputs. This is useful for simulating angle-of-arrival (AoA)
and phased array antenna wavefronts.

Synchronization input connections

10 MHz input Accepts a basic external reference at 10 MHz. Achieves lower residual phase noise than a 10 MHz input at the
system sync input. See the Rear Panel Connectors Section for connection details.
System sync input Recommended external reference input for use in system environments where trigger jitter and phase stability
are important. Accepts a wide variety of input frequencies. See the Rear Panel Connectors Section for connection
details.
6 GHz input Provides high stability synchronization between multiple signal generators. This is not a general 6 GHz connection.
Only the 6 GHz synchronization output from another compatible signal generator should be connected. See the
Rear Panel Connectors Section for connection details.
Synchronization output connections
10/100 MHz output Provides a basic external reference at 10 MHz or 100 MHz. Achieves better spectral purity than the system sync
output. See the Rear Panel Connectors Section for connection details.
System sync output Recommended external reference output for use in system environments where trigger jitter and phase stability
are important. Normally provides a 250 MHz output, but other frequencies are available. See the Rear Panel
Connectors Section for connection details.
6 GHz output Provides high phase stability synchronization between multiple signal generators. See the Rear Panel Connectors
Section for connection details.
System sync input
Frequency 1 to 250 MHz in 1 MHz steps. Default value is 250 MHz.
Lock range ± 1.0 ppm (nom)
Amplitude 6 dBm ± 6 dB (nom). To optimize phase noise use 6 dBm ± 2 dB (nom).
Input impedance 50 Ω (nom)
Usage The input frequency is not auto-detected. It must be entered manually and must be accurate to within the lock
range above.
System sync output
Frequency 10 MHz, 100 MHz, or 250 MHz, selectable. Multi-box synchronization overrides this selection and may use other
frequencies.
Amplitude 12 dBm (nom)
Output impedance 50 Ω (nom)
6 GHz input
Frequency 6 GHz
Lock range ± 1.0 ppm (nom)
Amplitude 11 dBm ± 6 dB (nom)
Input impedance 50 Ω (nom)
Usage This input must be connected to the 6 GHz output (described below) or a similar output from another compatible
signal generator. The signal generator will not function without a 6 GHz signal at this input.
6 GHz output
Frequency 6 GHz
Amplitude 17 dBm (nom)
Output impedance 50 Ω (nom)
Usage A rigid jumper cable is provided to connect the 6 GHz output to the 6 GHz input. The jumper can be removed
to distribute this signal to other equipment. When distributing this signal to multiple UXG signal generators,
approximately 12 dB of loss is permissible before distribution amplifiers are required. One of the distributed
outputs from a master signal generator must be connected back into the 6 GHz input of the master signal
generator.
Reference bandwidth
Standard 25 Hz
Option EP1 25 Hz, 75 Hz, 400 Hz, or 2 kHz, selectable

Normal mode
Normal mode is optimized for maximum update rate (throughput). If the fast control port (FCP) Option CC1 or CC3 is installed, it
provides the capability to use pulse descriptor words (PDWs) to control frequency, amplitude, phase, pulse (include chirp or phase
coding), and FM or M. The PDW is streamed into the rear-panel FCP 100-pin connector using 46-bit wide control words. The control
word information is executed synchronously upon receipt of a trigger.

Fast CW mode
Fast CW mode is optimized for minimum latency. The FCP control over signal attributes is limited to CW frequency switching and the
addition of FM/ M provided this option was purchased. It is typically used with the FCP Option CC2 for compatibility with instruments
used in legacy test systems.

PDW Streaming mode

Streaming provides agile control of most of the instrument settings via a continuous stream of PDWs transferred from the internal
SSD or an external source, such as a LAN or the Fast Control Port. The set of parameters controlled by Streaming include frequency,
frequency band map, band adjust, relative power, phase, phase mode, pulse width, pulse start time, FM (chirp) and PM (phase coding).
Each PDW consists of seven 32-bit words. The streaming PDW parameters are executed asynchronously, based on the time stamp
information contained within the PDW.

list points where each list point contains multiple signal attributes. This mode supports dynamic sequencing using the external trigger
ports.
