38 SPCM Software
A typical main panel of a correlation measurement in the ‘Absolute Time’ mode is shown in
the upper row, left. It shows the photon numbers accumulated in four detection channels, the
intensity trace of one channel, correlation between two channels, and photon counting histo-
grams of two channels.
A TCSPC measurement is shown in the upper row, right. It shows a fluorescence decay curve
and an IRF recording. The recordings were taken in different ‘Measurement Pages’. The pan-
els of the ‘display parameters’ and the ‘trace parameters’ are kept open on the right.
The lower row, left, shows a combined decay/FCS measurement in the TCSPC FIFO mode. It
shows the decay curve, the intensity trace, and the FCS curve for one detector.
A measurement in the Multichannel Scaler mode is shown in the lower row, right. Two sub-
sequent measurements were recorded into subsequent ‘pages’ of the memory, and are dis-
played simultaneously.
Pleas note that the setup parameters for frequently configurations can be put in a list of ‘Pre-
defined Setups’, see ‘Predefined Setups’, page 51. Changing between different instrument
configurations is then a matter of a single mouse click, see below.
Changing Between Different Instrument Configurations
The complete instrument configuration is saved together with the data or setup files [2]. Thus,
the main panel configuration used for a particular experiment is restored when the correspond-
ing measurement or setup data are loaded. Moreover, you may put frequently used system
configurations into a list of ‘predefined setups’, see page 51. By using the panel shown in Fig.
59 you can change between different instrument configurations by a single mouse click.

Display and Trace Parameters
The display windows of the main panel are configured by the ‘Display Parameters’ the ‘2D
Trace Parameters’, and the ‘3D Trace Parameters’. The corresponding panels are shown in
Fig. 60.
