7 Formats and Data Flow
Reading Transfer Size
Each reading read from the output buffer in ASCII format is 23 bytes. Each
readings in REAL format is eight bytes.
Data Flow
The flow of measurement data within the counter is summarized in Figure 7-1.
Figure 7-1. Data Flow within the 53220A/53230A Counter.
Reading locations include the front panel, reading memory (volatile), output
buffer, internal flash memory (non-volatile), and external USB memory.
The commands which determine data flow are listed in Table 7-2 and are
described in the following paragraphs.
