Page 12: Pulse Generator
Waveform The Function button can be used to select the output function in the following order: - Sine - Triangle - Square - Sine - The current waveform is displayed on the screen. Enabling the output signal Pressing Function On/Off button enables/disables the output signal. In order to enable/disable the TTL output, the TTL button must be pressed. -
Page 13: Frequency Counter
Figure 4 Changing the parameters Frequency, Level See description from function generator. The same rules are applied for the pulse generator too. Level field displays the CMOS level of the pulse generator signal. The value with no load is displayed. Duty cycle The duty knob changes the duty cycle of the output signal between 10% and 90%, minimum step being 1%. - Page 14 Figure 5 Unipolar/Bipolar button: The type of the input signal can be changed anytime by pressing the Unipolar/Bipolar button. Description The Frequency counter module can measure the frequency of bipolar or unipolar signals. The term unipolar indicates that the signal swings from zero (ground) or a positive voltage to a higher voltage, and bipolar indicates that the signal swings above and below zero (ground).

Page 17: Logic Switches
Figure 9 Description PB-507 provides two open-collector output pulsers, each with 1 normally-open (NO) and 1 normally-closed (NC) output. When the pushbutton is released, the circuit is in NC state, and when the pushbutton is pressed, the circuit is in NO state. -
Page 18: Spdt Switches
Figure 10 Description PB-507 provides 8 logic debounced outputs with 2 user selectable logic families: CMOS and TTL. Each of the logic switches can be switched separately between logic high (red) and logic low (green) by pressing the buttons S7…S0. When CMOS is selected, the high level is determined by the +V voltage set for the DC power supply. -
Page 19: Logic Probe
Figure 12 Description • Eight bicolor LEDs (b7…b0) are used to indicate logic high (red) or low (green) for eight digital inputs. • The TTL or CMOS input switching levels can be selected by pressing button TTL/CMOS. The High and Low thresholds for CMOS depend on the positive voltage set in the DC Power supplies module. -
