BSLSTMB
BSLSTMA
Lab set up note
Placing the BSLSTMA/B unit too close to
MP3X hardware can result in data distortion
of the BSLSTMA/B pulse width signal; the
distortion is more apparent at higher sampling
rates.
•
NEVER set the BSLSTMA/B atop an
MP3X
•
Position the BSLSTMA/B away from the
MP3X to reduce the signal distortion
Note
The older “BSLSTM” uses dial reading and a flip range switch. The same guidelines and
cautions described here apply, except when noted.
The BSLSTM Stimulator works in conjunction with the Biopac Student Lab System to allow precise stimulus
pulse outputting. Use the BSLSTM and the BSL
PRO
to perform a wide array of measurements, such as:
▪
Twitch sub-threshold & threshold
▪
Muscle tension/length vs. force
▪
Fatigue
▪
Maximum twitch responses
▪
Tetanic contraction
▪
Velocity
▪
Single twitch, summation
▪
Nerve conduction
STIMULATOR PULSE DEFINITIONS
Pulse width
The time that the pulse is in the non-zero or active state.
Delay before first pulse
The initial delay from the start of acquisition to the start of the first pulse.
Repetition period
The time between pulses, as measured from the start of one pulse to the start
of the next pulse. This is the inverse of the Pulse rate.
Pulse rate
The number of pulses that occur in a one-second interval, expressed in Hz.
The
Pulse rate
relates to the
Pulse period
as follows:
