All specifications and characteristics apply under the following conditions, unless otherwise stated:
After 90 minutes of warm-up time, where the instrument is left in the ON state.
Over the 25 °C ± 5 °C temperature range.
For error-corrected specifications, over 23 °C ± 3 °C, with < 1 °C variation from calibration temperature.
For error-corrected specifications are warranted and include guard-bands, unless otherwise stated.
When a frequency is listed in two rows of the same table, the specification for the common frequency is
taken from the lower frequency band, except when the band edge is less than 5 GHz.
Specifications do not include effects of any user cables attached to the instrument.
Specifications may exclude discrete spurious responses.
All specifications apply with internal 10 MHz Crystal Oscillator Reference Signal.
All specifications are with Interpolation Mode Off.
Refers to instruments without Options 051, 061, or 062.
Typical performance indicates the measured performance of an average unit.
It does not include guard-bands and is not covered by the product warranty.
Typical specifications are shown in parenthesis, such as (-102 dB), or noted as Typical.
Characteristic performance indicates a performance designed-in and verified during the design phase. It
does include guard-bands and is not covered by the product warranty.
All uncertainties below 300 kHz are typical.
12 months (Residual specifications also require calibration kit calibration cycle adherence.)

a. Since Residual Load Match is limited by Residual Directivity and the user test port cable, it can only be specified as Residual Directivity. For
practical considerations, derate it by approximately 8 dB for a 3670 Series test port cable, to compensate for effects such as match,
repeatability, bend radius, and similar parameters.
MS4642B Measurement Uncertainties
The graphs give measurement uncertainties after the above calibration. The errors are a worst-case contribution of residual directivity, load and
source match, frequency response and isolation, network analyzer dynamic accuracy, and connector repeatability. 10 Hz IF Bandwidth is used. For
transmission uncertainties, it is assumed that S
measurements were performed at 0 dBm or default port power, whichever is less. For other conditions, please use our free Exact Uncertainty
Calculator software, available for download from the Anritsu web site at www.anritsu.com.

a. Since Residual Load Match is limited by Residual Directivity and the user test port cable, it can only be specified at Residual Directivity. For
practical considerations, derate it by approximately 8 dB for a 3670 series test port cable, to compensate for effects such as match,
repeatability, bend radius, and similar parameters.
MS4644B Measurement Uncertainties
The graphs give measurement uncertainties after the above calibration. The errors are a worst-case contribution of residual directivity, load and
source match, frequency response and isolation, network analyzer dynamic accuracy, and connector repeatability. 10 Hz IF Bandwidth is used. For
transmission uncertainties, it is assumed that S
measurements were performed at 0 dBm or default port power, whichever is less. For other conditions, please use our free Exact Uncertainty
Calculator software, available for download from the Anritsu web site at www.anritsu.com.
