LOGIC INDICATORS
16 LED’s 8 red to indicate logic high, 8 green to indicate a logic low.
 
LOGIC PROBE
Built-in TTL/CMOS compatible logic probe.
Captures fast single shot events and pulse trains.
Input impedance 300K•, overload protection +50VDC, min.. detectable pulse width 100nsec. TTL threshold low +0.8V high +2.25V, CMOS threshold low +30%Vcc high +70%Vcc. Memory mode, latches on first transition and LED remains on until probe is reset
   
DEBOUNCED PUSHBUTTONS (PULSER)
Two push-button operated, open-collector output pulsers, each with one normally-open and one normally- closed output. Each output can sink up to 25mA.
   
   
POTENTIOMETERS  
One 1K•, one 10K•, all leads available and uncommitted.  
     
SWITCHES  
Two SPDT slide switches, all leads available and uncommitted.  
     
LOGIC SWITCHES  
8 individual SPDT logic switches, one side of all eight switches connected and switchable to +5V or ground, other side of all eight switches separate, and uncommitted.  
     
BNC CONNECTOR  
Two BNC connectors, pin available and uncommit-ted, shell connected to ground.
