Part 6: IEEE 488.2 Command Reference
VOLT_DIV, VDIV
Description
The VOLT_DIV command sets the vertical sensitivity in Volts/div. Refer to the product datasheet at
teledynelecroy.com for a list of valid ranges.
The vertical sensitivity includes the attenuation factor (set by the command ATTN, default 1.0) and the
sensitivity of the probe attached to the channel input, if any.
If an out-of-range value is entered, the VAB bit (bit 2) in the STB register is set. Refer to the STB table in the
*STB? topic for more information.
The VOLT_DIV? query returns the vertical sensitivity of the specified channel at the probe tip.
Command Syntax
<channel>:VOLT_DIV <v_gain>
<channel>:= <C1 to Cn>
<v_gain>:= <any valid value><unit>
When specifying <v_gain>, the unit V is optional. Other units should be specified using the notation in Units
and Multipliers.
Query Syntax
<channel>:VOLT_DIV?
Response Format
<channel>:VOLT_DIV <v_gain>
Example (GPIB)
The following instruction sets the vertical sensitivity of channel 1 to 50 mV/div:
