A.1.3.19 Short Description

set analyzer clock.

A.1.3.20 Syntax

SC [timetag [frequency]]

timetag: One of these values:

OSC1MHZ (1 Mhz oscillator)

OSC2MHZ (2 Mhz oscillator)

OSC4MHZ (4 Mhz oscillator)

OSC8MHZ (8 Mhz oscillator)

OSC16MHZ (16 Mhz oscillator)

EXT (external clock)

BUS (bus clock)

PROGRAM (programmable clock)

frequency: Time tag clock frequency for the programmable clock, 50 Hz to 50 kHz

(enter a decimal hertz value). The programmable clock source has a fundamental

frequency of 500,000 Hz; the actual frequency the system uses is the quotient of
