The ESA-L Series spectrum analyzers are tested to ensure they will meet their warranted performance. Unless otherwise stated, all specifications are valid over 0 to 55 °C. Supplemental characteristics, shown in italics, are intended to provide additional information that is useful in using the instrument. These typical (expected) or nominal performance parameters are not warranted but represent performance that 80 percent of the units tested exhibit with 95 percent confidence at room temperature (20 to 30 °C). This data sheet is intended as a quick reference to ESA-L spectrum analyzer specifications, and is by no means complete. Please refer to the ESA-L specification guide for full information and specifications, publication number: E4403-90036.
