Test level of –3 dBm. No averaging. Bandwidth 10 Hz.

Ambient temperature equal to the calibration temperature.

A 12 error term calibration is assumed carried out with

a good-quality SMA or PC3.5 calibration kit capable of

achieving the performance specified.

These values are supplied with our Check Standard on USB

memory stick as uncertainty data file:

“Instrument Uncertainty with Pico Standard SMA leads 106.dat”

or:

“Instrument Uncertainty with Pico Standard SMA leads 108.dat”

Uncertainty files are installed with the software.

Spurious responses

–76 dBc typical, –70 dBc max.

The main spurious response occurs close to (2 x RF + 1.3) MHz

or (3 x RF + 2.6), where RF is the test frequency in MHz.

For example, when testing a bandpass filter with a centre

frequency of 1900 MHz, an unwanted response will occur

around 632.47 MHz or 949.35 MHz. In all known cases the

levels will be as stated.
