Definitions

General

Product data applies under the following conditions:

• Three hours storage at ambient temperature followed by 30 minutes warm-up operation

• Specified environmental conditions met

• Recommended calibration interval adhered to

• All internal automatic adjustments performed, if applicable

Specifications with limits

Represent warranted product performance by means of a range of values for the specified parameter. These specifications are marked with limiting symbols such as <, , >, , ±, or descriptions such as maximum, limit of, minimum. Compliance is ensured by testing or is derived from the design. Test limits are narrowed by guard bands to take into account measurement uncertainties, drift and aging, if applicable.

Specifications without limits

Represent warranted product performance for the specified parameter. These specifications are not specially marked and represent values with no or negligible deviations from the given value (e.g. dimensions or resolution of a setting parameter). Compliance is ensured by design.

Typical data (typ.)

Characterizes product performance by means of representative information for the given parameter. When marked with <, > or as a range, it represents the performance met by approximately 80 % of the instruments at production time. Otherwise, it represents the mean value.

Nominal values (nom.)

Characterize product performance by means of a representative value for the given parameter (e.g. nominal impedance). In contrast to typical data, a statistical evaluation does not take place and the parameter is not tested during production.

Measured values (meas.)

Characterize expected product performance by means of measurement results gained from individual samples.

Uncertainties

Represent limits of measurement uncertainty for a given measurand. Uncertainty is defined with a coverage factor of 2 and has been calculated in line with the rules of the Guide to the Expression of Uncertainty in Measurement (GUM), taking into account environmental conditions, aging, wear and tear.

Device settings and GUI parameters are indicated as follows: “parameter: value”.

Typical data as well as nominal and measured values are not warranted by Rohde & Schwarz.

Phase coherence (R&S®SMW-B90 option)

The R&S®SMW-K90 option provides phase-coherent RF outputs for the two RF paths or two or more instruments. For frequencies above 200 MHz, the LO output and input frequency are set to the output frequency.

LO coupling modes This mode corresponds to internal

LO operation in path A and path B. This mode corresponds to internal LO operation in path A, and LO of path B is coupled to path A. This mode corresponds to external LO operation at the LO IN connector in path A and internal LO operation in path B. This mode corresponds to external LO operation at the REF/LO IN connector in path A and path B.

REF/LO OUT states The active LO signal of path B can be

routed to the LO OUT connector (in order to couple two or more instruments).

= 10 kHz, deviation  half of maximum deviation

mod

internal < (1.5 % of reading + 20 Hz) external < (2.0 % of reading + 20 Hz)

FM distortion f

= 10 kHz, deviation = rm × 1 MHz < 0.1 %
