A method and system are presented for facilitating a PXE-compliant (Preboot Execution Environment) remote boot process between clients and multiple available servers on a network. Each server device can respond to a PXE-extended DHCP (Dynamic Host Configuration Protocol) Request message from any client device on the network. Each client can receive responses from the alternate servers, select a server from one of those responses, and be directed by that response to complete the remote boot process from the same server. Each server also employs a self-throttling process to prevent the server from responding to new PXE-extended DHCP request messages from additional clients while the server has insufficient resources to remote boot additional clients with the required quality of service. This automatically redirects those additional clients to other servers that can provide the required quality of service without affecting the remote boot of clients already being serviced by the server.

In order to measure the phase jitter of a high-frequency signal, a spectrum analyzer is used. The high-frequency signal (HF) to be measured is either multiplied by M and/or the output frequency of the variable frequency oscillator of the spectrum analyzer is divided by N, and both signals are set to the same frequency and mixed in a mixer. The output signal of the mixer is then evaluated in the preferably digital evaluating device of the spectrum analyzer according to the Fast Fourier Transformation principle. To this end, the spectrum analyzer requires only one additional mixer, frequency divider and/or frequency multiplier.
