The date and time displayed is the 965DSP “system 
clock.”  See the “Set Clock” section on page 12 
for further information on setting the clock and for 
information on the format of the date and time. 
Use the blue keys to enter an alphanumeric ID. The 
ID may have up to fourteen characters. Because there 
are not enough keys for all twenty-six letters, each of 
the number keys (except “1”) also function as letter 
keys for ID entry. Whether a number or letter is entered 
depends on how many times the key is pressed. As an 
example, if the Ohms key is pressed once, the number 
“3” will be displayed. If the same key is pressed 
twice, the letter “d” will be displayed, three times 
for the letter “e”, and four times for the letter “f”. 
When the desired number or letter is displayed, press 
any other key to insert the next number or letter. 
This will cause the previously entered characters to 
move to the left making room for the new character. 
If the same key needs to be used multiple times in 
a row (i.e. to enter the sequence ‘ABC2’), press the 
[Up] arrow to insert multiple spaces to the left of the 
cursor. Use the [Left] arrow to position the cursor 
under the first space and enter the first character, and 
then use the [Right] arrow to move the cursor under 
the next space. Insert the next character and use the 
[Right] cursor again to position the cursor to the next 
position. Continue entering numbers or letters in this 
manner until all have been entered. If you enter more 
than 14 characters, the first entered character will be 
discarded. To change or delete any of the characters, 
use the [Right] or [Left] key to move the cursor 
under the letter to be changed or deleted. To delete 
the character, press the [Down] key. To change the 
character, press the key of the new character once (for 
a number) or several times (for a letter). Once the ID 
has been entered, press the [Enter] key to save the 
current TDR trace information unless the User Info 
option (see User Info Setup page 19) is enabled. 
If User Info is enabled, you will see another edit 
screen as shown
