The '''Tektronix THS720''' is a portable 100 MHz, 500 MS/s (each channel) dual-channel digital oscilloscope with isolated inputs.
The '''Tektronix THS720''' is a portable 100 MHz, 500 MS/s (each channel) dual-channel digital oscilloscope with isolated inputs.
There were two variants, the THS720 STD and the THS720A.   
 
The primary difference is that the THS720A will trigger from the DMM input.
There were two variants, the THS720 STD and the THS720A.  The primary difference is that the THS720A will trigger from the DMM input.
 
The '''THS720P''' includes features for electrical/power electronics measurements.
 
[[Murlan Kaufman]] designed the THS700 series high voltage isolated front end.

Firmware is updated using the [[067-1436-00|067-1436-00 Communication Pod]] with an adapter cable via an internal connector.
A THS710A and THS720A can be upgraded to a THS720P with the removal of a few resistors on the main board (see pictures for details). No adjustment/calibration is required after this modification.
NOTE: A THS710STD can be upgraded to a THS720STD, but due to main board differences, these models CANNOT be upgraded to a -A or -P model<br>
Additionally, lower model scopes cannot be upgraded to a THS730A due to different input hybrid modules being used in the THS730A to provide the increased bandwidth.
==Replacement Accessories==
The DMM leads can be replaced with Mueller parts as used in the original lead kits 012-1482-00 for the standard set and ATLDX1 for the deluxe set as follows:

The cigarette lighter adapter is a standard 1.8m (6 foot) long cigarette lighter plug to 5.5mm x 2.1mm (Type A) center positive DC 'coaxial power connector' plug with red led and 1 A fuse.
The console cable and adapter, part numbers 012-1364-00 and 103-0403-00 can be replicated using an 8p8c RJ45 to female DB9 rewireable adapter and a 2 M long 8-conductor telephone type cable (wired pin 1 to 1, 2 to 2, etc) or Cat-5 Ethernet cable with a ferrite clipped near one end, sourced from ebay or the like.
The pinout for the adapter is as follows:
