Hardkey and Softkey Reference
Hardkey and Softkey Reference
This section contains an alphabetical listing of softkey and front-panel functions, and a brief description of
each function. The SERVICE MENU keys are not included in this chapter.
. is used to add a decimal point to the number you are entering.
− . is used to add a minus sign to the number you are entering.
up. is used to step up the current value of the active function. The analyzer defines the step size for different functions.
No units terminator is required. For editing a test sequence, this key can be used to scroll through and execute the
displayed sequence one step at a time.
down. is used to step down the current value of the active function. The analyzer defines the step size for different
functions. No units terminator is required. For editing a test sequence, this key can be used to scroll backwards
through the displayed sequence without executing it.
back. has two independent functions: 1) modifies entries and test sequences and 2) moves marker information off of
the graticules
backspace key. will delete the last entry, or the last digit entered from the numeric keypad. The backspace key can also
be used in two ways for modifying a test sequence: 1) deleting a single-key command that you may have pressed by
mistake, (for example A/R) and 2) deleting the last digit in a series of entered digits, as long as you haven't yet pressed
a terminator, (for example if you pressed Start 1 2 but did not press G/n, etc.). The second function of this key is to
move marker information off of the graticules so that the display traces are clearer. If there are two or more markers
activated on a channel on the right side of the display, pressing back will turn off the softkey menu and move the
marker information into the softkey display area. Pressing back, or any hardkey which brings up a menu, or a softkey,
will restore the softkey menu and move the marker information back onto the graticules.
∆ MODE MENU. goes to the delta marker menu, which is used to read the difference in values between the active
marker and a reference marker.
∆ MODE OFF. turns off the delta marker mode, so that the values displayed for the active marker are absolute values.
∆ REF = 1. establishes marker 1 as a reference. The active marker stimulus and response values are then shown
relative to this delta reference. Once marker 1 has been selected as the delta reference, the softkey label ∆ REF = 1 is
underlined in this menu, and the marker menu is returned to the screen. In the marker menu, the first key is now
labeled MARKER ∆ REF = 1. The notation “∆REF=1” appears at the top right corner of the graticule.
∆ REF = 2. makes marker 2 the delta reference. Active marker stimulus and response values are then shown relative
to this reference.
∆ REF = 3. makes marker 3 the delta reference.
∆ REF = 4. makes marker 4 the delta reference.
∆ REF = 5. makes marker 5 the delta reference.
∆ REF = ∆ FIXED MKR. sets a user-specified fixed reference marker. The stimulus and response values of the
reference can be set arbitrarily, and can be anywhere in the display area. Unlike markers 1 to 5, the fixed marker need
not be on the trace. The fixed marker is indicated by a small triangle ∆, and the active marker stimulus and response
values are shown relative to this point. The notation "∆REF=∆" is displayed at the top right corner of the graticule.
Pressing this softkey turns on the fixed marker. Its stimulus and response values can then be changed using the fixed
marker menu, which is accessed with the FIXED MKR POSITION softkey described below. Alternatively, the fixed
marker can be set to the current active marker position, using the MKR ZERO softkey in the marker menu.
1/S. expresses the data in inverse S-parameter values, for use in amplifier and oscillator design.
2X: [12]/[34]. sets up a two-graticule display with channel 1 and 2 on the top graticule and channels 3 and 4 in the
bottom graticule.
2X: [13]/[24]. sets up a two-graticule display with channel 1 and 3 in the top graticule and channels 2 and 4 in the bottom
graticule.
2.4mm 85056. selects the 85056A or the 85056D cal kit.
2.92* 85056K. selects the 85056K cal kit.
