PB-503 Bench-Top Workstation
- Limited lifetime warranty on all
breadboarding sockets & 3-year warranty on all parts and
- Ideal for analog, digital and microprocessor
- New high & low buffered logic indicators
- 8 channel logic monitor
- New 8 selectable logic switches
- Function Generator with continuously
variable sine, square and triangle waveforms and TTL pulses
- Triple output power supply offers
fixed 5 VDC supply plus two variable outputs: ▒1.3 to
- Two Digital Pulsers
- Audio experimentation speaker
- New removable breadboard area and
optional additional breadboard socket plates
- Multiple features in one complete
test instrument saves hundreds of dollars necessary for
3-wire AC line input (117V, 60 Hz typical) with
power-on indicator. Both Models are available in 220-240VAC@50Hz
Fixed DC output: +5V@1.0A, ripple <5mV. Variable DC output:
+1.3 V to +15V@0.5A, ripple <5mV. Variable DC output: -1.3V
to -15V @ 0.5A, ripple <5mV.
Frequency Range: 0.1 Hz to 100 kHz in
six ranges.Output voltage: 0 to ▒10V (20Vp-p). Output
Impedance: 600 ohms (except TTL). Output current: 10mA
maximum, short circuit protected. Output waveforms: sine,
square, triangle, TTL. Sine wave: distortion <3% (10Hz to
100kHz). TTL pulse: rise and fall time <25 nS. drive to 10
TTL loads. Square wave: rise and fall time <1.5ÁS
8 LED's, active high, 1.4 volt (nominal) threshold,
inputs protected to ▒20 volts.
DEBOUNCED PUSH-BUTTON (PULSERS):
Two pushbutton-operated, open-collector output
pulsers, each with one normally-open, one normally closed output.
Each output can sink up to 250 mA.
POTENTIOMETERS: One 1 K ohm, one 10 K
ohm, all leads available and uncommitted.
BNC CONNECTORS: Two BNC connectors, pin
available and uncommitted, shell connected to ground.
Two SPDT slide switches, all leads available
and uncommitted. 8-pole DIP switch: one side of all eight switches
connected and switchable to +5V or ground, other side of all eight
switches separate, available, and uncommitted.
SPEAKER: 0.25W, 8 ohms
Three UBS-100 sockets with 840 tie-points each
for a total of 2520 uncommitted tie-points. Two QT-59B Bus strips
internally connected to power and ground. Fifty tie-points each
for +5V, +V,=15 V and ground.
ENCLOSURE: High impact molded case.
