the r&s^®fs-k10 application firmware covers transmitter measurements of gsm, edge and edge evolution signals in line with the standards (3gpp ts 45.005, 51.010 and 51.021).

the option performs modulation and spectrum-related analysis in line with the 3gpp standard, e.g. calculation of phase/frequency/magnitude error, evm, i/q imbalance, spectrum due to modulation and spectrum due to switching transients.

it can be installed on the r&s^®fsq and r&s^®fsg signal and spectrum analyzers with windows xp (not supported on the r&s^®fsq with the r&s^®fsq-b18 removable hard disk option).

after configuring the type and class of device (e.g. normal bts or small ms) as well as the frequency band and power class used, the test limits for spectrum due to modulation and due to switching transients as well as for power versus time are automatically configured in line with the standard, with pass and fail results.

after the “auto set” key has been pressed, r&s^®fs-k10 automatically detects the burst type, modulation type (gsmk, qpsk, 8psk, 16qam or 32qam) and the training sequence. the instrument is automatically configured and ready to perform all measurements; no additional configuration is needed.

the modulation accuracy table provides a quick overview of the most important numeric parameters. it is derived from the selected slot in the capture buffer.

additional measurements, e.g. of phase or magnitude error versus time, or evm versus time and the constellation diagram, provide enhanced analysis capabilities.

all functions can be remote-controlled by scpi commands either via gpib (ieee 488) bus or lan interface.
