Description<br />

The SRCTK comm<strong>and</strong> adjusts the tracking of the tracking-generator output relative to the<br />

center frequency of the spectrum-analyzer. SRCTK is used typically for b<strong>and</strong>widths less than<br />

300 kHz. B<strong>and</strong>widths greater than 300 kHz do not require tracking adjustment. Use SRCTK to<br />

improve amplitude accuracy <strong>and</strong> maximize signal response. Use SRCTKPK to adjust tracking<br />

automatically. See “SRCTKPK. n<br />
