THS710A, THS720A, THS730A & THS720P Service Manual
1–1
Specifications
This chapter contains the oscilloscope, DMM, and general specifications for the
THS710A, THS720A, THS730A, and THS720P TekScope instruments. All
specifications are guaranteed unless noted “typical.” Typical specifications are
provided for your convenience but are not guaranteed. Specifications that are
marked with the n symbol are checked in the chapter Performance Verification.
All specifications apply to all four instruments unless noted otherwise. All
specifications assume horizontal MAG is off, unless noted otherwise. To meet
specifications, two conditions must first be met:
H The TekScope instrument must have been operating continuously for ten
minutes within the operating temperature range specified.
H You must perform the Compensate Signal Path operation, accessible through
the utility menu, if the ambient temperature changes by more than 5° C.
