F108 – Oscillator Configuration
Use function F108 to display the type of oscillator being used:
• TCVCXO
•OCXO
• HIGH (High Stability OCXO)
• RUBIDIUM
For more descriptions of the oscillator types, see “P7: Oscillators” on page 223
.
Command Line
The oscillator type is defined by the hardware configuration of the clock, and is not configured through
the command line or keypad/display user interfaces. To request the oscillator configuration, enter:
F108<S><CR>
The XLi responds:
F108<S>OSCILLATOR<S>CONFIG<S><OSC><CR><LF>
where:
For example, enter the following string:
F108<CR>
The XLi responds (example):
F108 OSCILLATOR CONFIG HIGH_STAB_OCXO<CR><LF>
F110 – J1 Input (Time Code, TIET)
Note: Time Interval - Event Time (TIET) is an optional feature. If purchased at the same time as the XLi,
it comes enabled on the system. To purchase this option after you have purchased the XLi, con-
tact Symmetricom Sales. See “H: Sales and Customer Assistance” on page 295.
F110 can configure the J1 input port on the main CPU card as a time code reference source for the
system clock, or it can configure J1 as the input for TIET operation.
F = ASCII character F
108 = Function number
<S> = ASCII space character one or more
<CR> = Carriage Return, equivalent to pressing the Enter key on a keyboard
<OSC> = Oscillator type: TCVCXO, OCXO, HIGH_STAB_OCXO), or RUBIDIUM
