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 50°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 that is not covered by the

product warranty. 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 vector adapters.

All options referenced in this data sheet are described in the UXG vector adapter configuration

guide (5992–2332EN).

This is a combined data sheet for the N5194A UXG Vector Adapter and the N5192A

UXG

Vector Adapter, Modified version. Unless otherwise stated, all specifications, typical, nominal and

measured values described in this data sheet will be the same for the N5194A and N5192A and

apply:

– When the N5194A UXG vector adapter is used together with the N5193A UXG agile signal

generator with options EP1 enhanced phase noise, FR1 fine frequency resolution, SS2/SS4

switching speed, and CC1 LVDS I/O interface.

Note:

– The minimum options required for proper operation are SS2/SS4 switching speed and

the CC1 LVDS I/O interface.

– The N5194A UXG agile vector adapter 40 GHz model (option 540) only requires a 20 GHz

N5193A UXG agile signal generator to operate over its full 40 GHz frequency range.

– When the N5192A UXG vector adapter is used together with the N5191A UXG agile signal

generator with options FR1 fine frequency resolutions, SS3 switching speed and CC1 LVDS

I/O interface.

Note: The minimum options required for proper operation are SS3 switching speed and the

CC1 LVDS I/O interface.

The N5193A and N5191A provide the 6 GHz reference and LO signals necessary for operating the

N5194A and N5192A respectively.

1. Unless otherwise noted, this data sheet applies to units with serial numbers ending with xx6006xxxx or greater.

2. Because of the high-performance characteristics of the N5194A, a U.S. export license is required. The N5192A

is a modified version of the UXG agile vector adapter that provides high performance without requiring an

export license. Notable differences include maximum available frequency and switching speed.

1. RF CW switching speed using an external hardware trigger. Speeds apply for any combination of frequency, amplitude ≤ max specified power and phase

switching.

2. For indexed waveform mode and real-time pulse generation mode during PDW streaming operation, minimum pulse spacing is 240 ns. Certain frequency

transitions will result in longer spacing due to update rate (transition time) limitations as described on Page 3 and 4. Also refer to page 9 under “PDW

streaming” for more details.

1. Update Rate is determined by the transition time as measured from the start of the RF transition (where the frequency, amplitude and phase are undefined)

to RF amplitude and phase settled. Latency is measured from the input trigger to RF amplitude and phase settled. For frequency transitions with typical

transition times of 2.5 us or longer, pre-pulse PDWs must be injected prior to the desired RF pulse to create clean pulses (except when using Simulation

View). Detailed descriptions of these pre-pulse PDWs can be found in the User’s Guide in the “Pre-Pulse PDW” section.

2. Optimized Mode applies when switching start frequency is not within any of the following 3 zones: (0 to 2.5 GHz) or (6.5 to 8 GHz) or (10 to 11.5 GHz), or stop

frequency is not within any of the following 2 zones: (13 to 14 GHz) or (18.5 to 20 GHz).
