HP E42 manual 5328A Counter Specifications, Programmable Operation Channels a and B

Model 5328A

General Information

Table 1-3.5328A Counter Specifications

GENERAL

Power Requirements: 115 or 230 volts 60 or 400 Hz ac.

Display: Nine-digit LED.

Sample Rate: Variable from less than 2 milli- seconds to HOLD.

Arming: Rear panel ARM (ON-OFF) switch. Refer to operation for details.

Blanking: Unwanted zeros to left of most-

significant-digit are suppressed. Hold: HOLDS count between samples. Trigger Light: Indicates input is above trigger

level.

PROGRAMMABLE OPERATION (CHANNELS A AND B)

Includes independent selection of coupling, trigger slope, trigger level, and attenuator for each channel. Separate/Common A switch is programmable. Also, an invert feature switches Channels A and B; useful in all functions except Ratio B/A.

Trigger level is programmable in 10 mV steps in X1; 100 mV in X10; IV in X100.

Trigger level accuracy under remote control: X1: ±35 mV

X10: ±350 mV +2% of trigger level

X100: ±3.5V +2% of trigger level
